Scientists discover new species of dinosaur in Argentina



Palaeontologists shocked to find remains examples of herbivore living in what was likely a desert 


Palaeontologists have unearthed the remains of a previously unknown species of dinosaur that lived 110 million years ago in Argentina.

The remains of three separate members of the new species, an adult and two juveniles, were discovered by a team of Spanish and Argentinian scientists at a site in Neuquen in the centre of the South American country.

The new species, named Lavocatisaurus agrioensi, is a member of the herbivourous group of dinosaurs known as sauropods, which includes the likes of the diplodocus and brontosaurus.
Scientists said remains that belonged to the adult suggested it would have been around 12 metres in length, while both the young discovered were between six and seven metres long.

“We found most of the cranial bones: the snout, the jaws, a lot of teeth, also the bones that define the eye sockets for example and, in that way, we were able to create an almost complete reconstruction,” Jose Luis Carballido, a researcher at the Egidio Feruglio museum told Agence France-Presse.

“Not only is this the discovery of a new species in an area where you wouldn't expect to find fossils, but the skull is almost complete.”

New dinosaur species named in honor of Ghostbusters monster

May 10, 2017

by Chuck Bednar

A newly-identified species of ankylosaur sporting a horned face and a spiked, club-like tail has been named in honor of Zuul, the monstrous demigod featured in the 1984 movie Ghostbusters, according to new research published this week in the journal Royal Society Open Science.

Take one look at the new species, officially named Zuul crurivastator, and it’s easy to see why the paleontologists who discovered it chose to name it after the fictional beast: it bears a striking resemblance to the entity that possessed Sigourney Weaver’s character Dana Barrett in the film. “We couldn’t resist,” Dr. Victoria Arbour, a postdoctoral fellow at the Royal Ontario Museum and the University of Toronto and one of the researchers who discovered the new species, told USA Today. In fact, they even brought in Dan Aykroyd, who played Ray Stanz in the movie, to introduce the creature and discuss its similarities to Zuul in a short video.

“We are so honored that the Royal Ontario Museum would accord the name of this magnificent creature with the appellation that we called our terror god in the movie,” Aykroid said.

The new species was discovered in Hill County, Montana and is believed to be approximately 75 million years old, the Museum explained on its website. Its entire body was covered in scales and it was about 20 feet long with a roughly 10-foot tail, according to Los Angeles Times reports.

New species of dinosaur increases the already unexpected diversity of 'whiplash dinosaurs'

Researchers from Italy and Portugal describe yet another new sauropod species from 150 million years ago, from Wyoming, USA

The new species, Galeamopus pabsti, is the most recent dinosaur to be described by paleontologists from the Department of Earth Sciences of the University of Turin, Italy; the Faculty of Science and Technology, Universidade Nova de Lisboa, and the Museum of Lourinhã in Portugal. This Jurassic dinosaur was originally excavated in 1995 by a Swiss team, led by Hans-Jakob "Kirby" Siber and Ben Pabst, in Wyoming, in the United States and is the latest in a series of new discoveries by the paleontologists Emanuel Tschopp and Octávio Mateus, which started in 2012 with Kaatedocus siberi. The paper describing the new species was published online in the open access scientific journal PeerJ on Tuesday, May 2.

Galeamopus pabsti is similar to the famous dinosaur Diplodocus, but with more massive legs, and a particularly high and triangular neck close to the head. It is the second species of the genus Galeamopus to be shown to be different to Diplodocus by the same researchers (the first being published in 2015, in a paper which also reinstated the brontosaurus as a distinct genus). The new species is dedicated to Ben Pabst, who found the skeleton, and prepared it for mounting at the Sauriermuseum Aathal in Switzerland, where it is one of the main attractions of the permanent exhibit.

Dinosaur's Curious Back Sail May Have Aided Migration

by Laura Geggel, Staff Writer | December 16, 2015 03:00pm ET

The bizarre rigid "sail" on the back of a newfound species of herbivorous dinosaur may have helped the paleo-beast survive in a variety of climates, a new study finds.

The dinosaur lived during the Early Cretaceous period about 125 million years ago in ancient Spain, the researchers said. During that time, some areas of Iberia had alternating wet and dry periods. Perhaps the dinosaur used its sail to regulate its body temperature, much like an elephant uses its large ears to release excess body heat, the researchers said.

Or, the dinosaur could have used the sail as a place to store fat to use when resources were scarce, the scientists said.

Ancient Footprints Show Dinosaur Duo Strolling Along the Beach

by Laura Geggel, Staff Writer | August 13, 2015 07:26am ET

About 142 million years ago, two carnivorous dinosaurs wandered along a beach and left their large footprints behind in the sand, a new study finds.

These footprints, now fossilized, are helping researchers understand what types of dinosaurs lived in what is now modern-day northern Germany. The tracks show that one dinosaur was large, and the other small. Their prints suggest they walked at a slow, strolling pace — about 3.9 mph (6.3 km/hour) for the large one and about 6 mph (9.7 km/h) for the little one.

At some points, the small dinosaur began trotting, possibly to keep pace with the large one. The footprints also indicate the dinosaurs skid here and there, likely slipping on the wet sand, said study researcher Pernille Troelsen, who earned her master's degree in biology from the University of Southern Denmark in June.

Huge Dinosaur Thighbone Found on Washington Beach

by Laura Geggel, Staff Writer | May 20, 2015 03:10pm ET

A fragmented femur bone hidden underwater for millions of years has become the first evidence that a dinosaur once roamed Washington, a new study finds.

And not just any dinosaur: This beast was a theropod — a two-legged, mostly meat-eating group of beasts, such as Tyrannosaurus rex and Velociraptor, that are related to modern-day birds, the researchers said.

Scientists found the 80-million-year-old fossil of the dinosaur when they were searching for ammonites — extinct marine invertebrates with spiral shells — and other fossilized animals. They had focused their fieldwork in the San Juan Islands, an archipelago located a short ferry ride away from the Seattle area. [See Images of the Fossil of the First Dinosaur Found in Washington]

New horned dinosaur species identified from museum's fossils


A new species of horned dinosaur has been identified from fossils held in a Canadian museum for 75 years.

The fossils had previously been classified as belonging to a different dinosaur group.

But Nick Longrich, from the University of Bath, found they closely resembled a dinosaur from the south-west US.

He says the remains represent a new species of the dinosaur Pentaceratops - a smaller cousin of the familiar horned plant-eater Triceratops.

Details of the research have been published in the journal Cretaceous Research.

'Undiscovered dinosaurs'
The paper contains a formal description of the animal including its new name - Pentaceratops aquilonius.

It was a buffalo-sized plant eater that lived from about 75 million years ago.

Dr Longrich also studied another horned dinosaur held within the museum's collection.

Dino-Era Mammal Had Excellent Hearing, Rare Skull Reveals

by Laura Geggel, Staff Writer | November 05, 2014 02:47pm ET

Dinosaurs that lumbered around the ancient supercontinent Gondwana had a warm-blooded neighbor — a "chewing machine" with big eyes, excellent hearing and an acute sense of smell, according to a new study.

A team of researchers led by David Krause, a professor of anatomical sciences at Stony Brook University in New York, serendipitously discovered the skull of the primitive mammal (Vintana sertichi) in Madagascar in 2010, while searching for fossils of aquatic creatures. It belongs to a group of elusive extinct mammals called gondwanatherians, which scientists had previously only known about from several teeth andlower jaw fragments.

The newly discovered and well-preserved skull reveals details about the mysterious mammal, which lived about 72 million to 66 million years ago.

Super Schnozzle: Dinosaur with Exceptionally Large Nose Discovered

By Jeanna Bryner, Managing Editor | September 22, 2014 01:10pm ET

The remains of a big-nosed dinosaur that stalked the Earth some 75 million years ago, possibly luring mates with its beauty of a schnozzle, have been discovered in central Utah.

The beast's giant nose earned the dinosaur the name Rhinorexcondrupus, with the Latin word Rhinorex meaning "king nose." And it surely sported a large sniffer, having the largest nasal opening, relative to its size, of any duck-billed dinosaur and among the largest of any dinosaur, according to Terry Gates, a joint postdoctoral researcher with NC State and the North Carolina Museum of Natural Sciences.

"The purpose of such a big nose is still a mystery," Gates said in a statement. "If this dinosaur is anything like its relatives then it likely did not have a super sense of smell; but maybe the nose was used as a means of attracting mates, recognizing members of its species, or even as a large attachment for a plant-smashing beak."

Experts discover first Venezuelan dinosaur - via The Anomalist

11th August 2014 

An international team of experts, including scientists from the Natural History Museum and the University of Zurich, have discovered the first new dinosaur species in Venezuela. It's also the first found in the northern part of South America. La Quintasaura - as it's named - was around the size of a small dog, and had a diet of green ferns and the occasional insect.

They're hundreds of millions of years old, yet new species are still being discovered each year.

Fox-Sized Relative of Triceratops Discovered in Venezuela

By Charles Q. Choi, Live Science Contributor | August 05, 2014 07:01pm ET

The fossil of a new two-legged, fox-sized dinosaur relative of both Stegosaurus and Triceratops, which dates back about 200 million years, has been discovered in Venezuela. The find suggests that dinosaurs advanced quickly across the globe after a mass extinction claimed at least half of all species on Earth, researchers say.

This new fossil, the first named dinosaur unearthed from northern South America, also provides evidence that dinosaurs lived in herds early on in their evolution, and were able to dwell in regions previously thought too inhospitable for dinosaurs to survive.

The new dinosaur is named Laquintasaura venezuelae. Laquintasaurais Greek for "lizard of La Quinta," the rock formation where the reptile was discovered in the Andes, while venezuelae refers to the country of Venezuela, where the dinosaur was unearthed. [See Images of the Newfound Little Dinosaur]

'Biggest dinosaur ever' discovered

17 May 2014 Last updated at 01:50

By James Morgan
Science reporter, BBC News

Fossilised bones of a dinosaur believed to be the largest creature ever to walk the Earth have been unearthed in Argentina, palaeontologists say.

Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall.

Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus.

Scientists believe it is a new species of titanosaur - an enormous herbivore dating from the Late Cretaceous period.

A local farm worker first stumbled on the remains in the desert near La Flecha, about 250km (135 miles) west of Trelew, Patagonia.

Ferocious dino was European giant

By Jonathan Amos
Science correspondent, BBC News

Scientists in Portugal have identified what they think may have been the largest predator ever to roam across the European landmass.

Fossil bones from the dinosaur were pulled from a cliff at Praia da Vermelha just north of Lisbon.

Known as Torvosaurus gurneyi, this ferocious beast would have been some 10m in length and weighed perhaps 4-5 tonnes.

Its features are described in the latest edition of the Plos One journal.

It was a theropod - the kind of two-legged, meat-eating animal that everyone instantly recognises in something like Tyrannosaurus rex.

But T. gurneyi lived much earlier in time, in the late Jurassic - about 150 million years ago.

"We all know about T. rex, but Tyrannosaurus was a Cretaceous animal," explains co-author Prof Octavio Mateus from the New University of Lisbon.


"Our dinosaur was Jurassic. The difference in age is striking - it's 80 million years. So, when T. rex walked on Earth, Torvosaurus was already a fossil," he told BBC News.

Mokele-Mbembe

For over 2 hundred years there have been reports of a living dinosaur in Africa. This creature, which the natives call "Mokele-Mbembe" is believed to be a sauropod type of dinosaur.

Sauropod means "Lizard-Footed" dinosaur. Sauropods are four-legged, herbivorous dinosaurs

These incidents were reported long before the word "dinosaur" was coined, and long before anyone (in this century) knew they existed. If Mokele-Mbembe is a living dinosaur, then it makes the claim of total dinosaur extinction unfounded.

The Congolese people are very familiar with the aquatic dinosaur living in the Likoula swamp region. They call this Apatosaurus-like creature "Mokele-Mbembe" which means: "one who stops the flow of rivers".

From the size of this awesome beast this name is sure fitting!

They believe this animal (which they greatly fear) is sacred. 
This belief is due to the illness and death of many in the pygmy tribe after one was killed with a spear and eaten by the people.

Of course, the deaths and illness were probably more likely due to spoilage of its meat. An animal this large could have been eaten for several weeks.

Small, Speedy Plant-Eater Extends Knowledge of Dinosaur Ecosystems

May 22, 2013 — Dinosaurs are often thought of as large, fierce animals, but new research highlights a previously overlooked diversity of small dinosaurs. In the Journal of Vertebrate Paleontology, a team of paleontologists from the University of Toronto, Royal Ontario Museum, Cleveland Museum of Natural History and University of Calgary have described a new dinosaur, the smallest plant-eating dinosaur species known from Canada. Albertadromeus syntarsus was identified from a partial hind leg, and other skeletal elements, that indicate it was a speedy runner. Approximately 1.6 m (5 ft) long, it weighed about 16 kg (30 lbs), comparable to a large turkey.

Albertadromeus lived in what is now southern Alberta in the Late Cretaceous, about 77 million years ago. Albertadromeus syntarsus means "Alberta runner with fused foot bones." Unlike its much larger ornithopod cousins, the duckbilled dinosaurs, its two fused lower leg bones would have made it a fast, agile two-legged runner. This animal is the smallest known plant-eating dinosaur in its ecosystem, and researchers hypothesize that it used its speed to avoid predation by the many species of meat-eating dinosaurs that lived at the same time.

Albertadromeus was discovered in 2009 by study co-author David Evans of the Royal Ontario Museum as part an on-going collaboration with Michael Ryan of the Cleveland Museum of Natural History to investigate the evolution of dinosaurs in the Late Cretaceous of North America. The known dinosaur diversity of this time period is dominated by large bodied plant-eating dinosaurs.

Dinosaur 'fills fossil record gap'


By Helen Briggs, BBC News
Dinosaur fossils unearthed in Madagascar are of a new species that roamed the Earth about 90 million years ago, say US researchers.

The remains date back to a time when India and Madagascar were one landmass cut off from the rest of the world.

Revealing the discovery in the journal PLOS ONE, scientists say the dinosaur was a bi-pedal meat-eater about the size of a large cow.

It has been named Dahalokely tokana, which means "lonely small bandit".

Madagascar is a treasure trove for palaeontologists, yielding thousands of well-preserved fossils.

“This just reinforces the importance of exploring new areas around the world where undiscovered dinosaur species are still waiting,” Joe SertichDenver Museum of Nature and Science

But the latest discovery is the first new dinosaur species unearthed on the island in almost a decade.

Its Malagasy name refers to its carnivorous diet and isolation on a landmass in the middle of the ocean.

The discovery fills a gap in the fossil record and raises intriguing questions about the evolution of animals on both Madagascar and India, which separated at about the time this newly identified creature walked the Earth.

Andrew Farke of the Raymond M Alf Museum of Paleontology in Claremont, California, says it belongs to a group called the Abelisauridae, which were common to the southern continents.

Explorers embark on hunt for 'African Loch Ness Monster' Mokele-mbeme


This modern-day dinosaur is believed to live in the jungle rivers of the Congo in Africa.

Now a team of explorers is setting out to discover once and for all whether Africa’s monster is fact or fiction.
 
The team of dino hunters arrived in the Congo capital of Brazzaville on Tuesday with an array of firearms for protection. 

‘It would be wholly unwise to travel where we are going without firearms,’ said spokesman for the group Joe Marrero, 28.

‘We plan to be in the jungle for three months searching for the mokele and other new species and can only carry so much food.’

He and two others - expedition leader and biologist Stephen McCullah, 21, and Sam Newton, 22, all from the US - begin their search next month.

Over 80 per cent of Congo remains unexplored, according to recent government figures.

'Lake creature' pops up in Mpls park


MINNEAPOLIS (AP) — Don't be alarmed if you see a lake creature bobbing in Wirth Lake in Minneapolis this summer. It's only a whimsical sculpture that looks like a dinosaur.

Minne (MIN'-nee) the Lake Creature is taking up residence in the popular lake in Theodore Wirth Park through September.

It's the first time Minne will moor in a single lake for the entire season. The 13-foot fiberglass sculpture has visited two or more Minneapolis lakes in previous years, for a total of 16.

Minneapolis sculptor Cameron Gainer was inspired by the famous 1934 "Surgeon's Photo" of the Loch Ness Monster when he created Minne. The sculpture first showed up in 2009 in Lake Harriet.

Minne is an annual public art project of the Minneapolis Parks Foundation.
