A fossil previously discovered in
a quarry at Nottinghamshire, England has been identified as a new species of
ichthyosaur – an extinct marine reptile which dates back some 200 million years
to the earliest part of the Jurassic Period – according to new research published Monday.
The fossil was identified by Dean
Lomax, a paleontologist at the University of Manchester who
explained that the creature is one of just a few ichthyosaur species dating
back to that era, which makes the discovery of this dolphin-like creature very
significant to the scientific community.
It also marks the first time that
a species this ancient has been located in the UK in a place other than Dorset
and Somerset, he noted. Lomax examined the specimen while visiting the New Walk Museum in Leicester, which
acquired the partially-complete skeleton of the creature in 1951.
“When I first saw this specimen,
I knew it was unusual,” he said in a statement. “It displays features in the bones –
especially in the coracoid (part of the pectoral girdle) – that I had not seen
before in Jurassic ichthyosaurs anywhere in the world. The specimen had never
been published, so this rather unusual individual had been awaiting detailed
examination.”

ichthyosaur specimen in 30 years
The creature was represented by a
skull, pectoral bones, pelvic bones, limbs, ribs, and vertebrae, the university
said. While relatively complete, the remains were described as “disorderly,” as
it appeared as though the carcass had settled into the seabed prior to becoming
fossilized.
