April 2014: Large marine creatures that roamed the Earth’s oceans more than 520 million years ago have been found to filter food from the water in a similar way to today’s blue whales and evolved into a gentle sea giant from a large marine predator that fested on large prey say scientists.
Newly discovered fossils from North Greenland showed that these ancient giant marine animals used bizarre facial appendages to trawl for nekton and plankton from the seas.
The North Greenland fossil, called Tamisiocaris, was a member of the iconic anomalocarids group of early marine animals which roamed the Cambrian and later Ordovician oceans. They swam using a set of flaps down either side of the body and probably captured large prey with specialised grasping appendages in the front of the mouth.
