Fossils of the “sea monster” were found during an excavation in the state of Wyoming in 1995. The remains were on display at the Glenrock Museum of Paleontology.
The research, published yesterday in the peer-reviewed scientific journal iScience, examined these remains, which make up 35 percent of the creature’s body. Scientists had the lower jaw, part of the skull, parts of the neck, vertebrae, tail and ribs in their hands.
It was determined that the animal, which was determined to be 7 meters long, had different physical characteristics from other plesiosaurs.
The paper’s lead author, Walter Scott Persons IV, said that plesiosaurs generally have two distinct morphological types. One of them is the small-headed, snake-like neck type. The other is a crocodile-like long jaw with a short neck.
According to Independent Turkish, Scott Persons, “This strange, unique beast is a cross between the two. said.
19 teeth and jaws from S. pfisterae confirmed that the creature was another species of plesiosaur.
The paleontologist said he was in middle school when he first saw the remains of S. pfisterae, and said the study shows a brand new ecotype that also evolved differently from other plesiosaurs living in the Pierre Shale formation.
Pierre Shale is thought to date from the Upper Cretaceous Period, about 101 million to 66 million years ago.
