Researchers identify ‘snaky croc-faced’ sea creature of Wyoming’s distant past
Seventy million years ago, an approximately 23-foot-long beast was swimming around Wyoming, whipping around its long neck and crocodile-like head in search of prey, which it would snatch up with 2-inch-long teeth.
That newly identified prehistoric marine reptile is now being called Serpentisuchops pfisterae, which researchers say roughly translates to "snaky croc-face."
“Sounds like one of the insults the French knights would’ve wielded in Monty Python and the Holy Grail,” said Scott Persons, a paleontologist and College of Charleston professor who led the research team that discovered the critter. They described it in a paper published Monday in the journal iScience.
Persons said it was originally dug up in the mid-'90s before years of processing – with help from some Wyoming volunteers.
“A team that is affectionately referred to as the ‘Glenrock Bone Biddies,’ because they’re a group of elderly women that have actually formed the equivalent of a paleontological sewing circle around picking at fossil bone,” Persons said.
What’s new about this old creature is that it has both a long neck and crocodile-like jaw. Usually, plesiosaurs just have one or the other, Persons said, and he theorized this one likely went after small, fast prey.
“We think it was using its long, very flexible and also very muscular neck to swish to the side very quickly to snag at prey and that the long crocodilian-like jaws served to further extend its reach,” he said.
Persons said such creatures that experienced their own changing climate can even teach us about our fast-changing world today.
