“About the size of a cow” New prehistoric sea creature discovered after Montana hunter finds exposed fossils
“A fossil found by an elk hunter in Montana nearly seven years ago has led to the discovery of a new species of prehistoric sea creature that lived about 70 million years ago in the inland sea that flowed east of the Rocky Mountains.
The new species of elasmosaur is detailed in an article published Thursday in the Journal of Vertebrate Paleontology. Most elasmosaurs, a type of marine reptile, had necks that could stretch 18 feet, but the fossil discovered in the Charles M. Russell National Wildlife Refuge is distinct for its much shorter neck – about 7½ feet.
“This group is famous for having ridiculously long necks, I mean necks that have as many as 76 vertebrae,” said Patrick Druckenmiller, co-author of the article and a paleontologist with the University of Alaska Museum of the North. “What absolutely shocked us when we dug it out – it only had somewhere around 40 vertebrae.”
The smaller sea creature lived around the same time and in the same area as the larger ones, which is evidence contradicting the belief that elasmosaurs did not evolve over millions of years to have longer necks, co-author Danielle Serratos said.
Elasmosaurs were carnivorous creatures with small heads and paddle-like limbs that could grow as long as 30 feet. Their fossils have been discovered across the world, and the one discovered in northeastern Montana was well-preserved and nearly complete.
The refuge adjacent to the Missouri River is popular with hunters for its big game and remote setting.
David Bradt, a ranch manager from Florence, Montana, said he was hunting elk unsuccessfully in November 2010 when he walked into a canyon to splash some water on his face.
In the creek, the water ran over what he thought was petrified wood sticking out of a rock. He pulled back the brush, saw vertebrae and knew it was fossilized bones.” (…) READ MORE
