Paleontologists gain insight into a dinosaur’s stern

(Reporter)
It’s the first time in palaeontology, which might produce a laugh. For the first time, scientists have been able to describe a dinosaur’s cloaca in fine detail. If you are not familiar with this part of the body, CNET Translates: It’s basically “the botuth of all trades.” The study was published Tuesday at Current biology It relates to a grass the size of a dog that lived about 120 million years ago Psittacosaurus. Scientists from the University of Bristol wrote that “it was previously indicated that the cloacal region has been preserved” although settled in this fossil, which was found decades ago in China, but the detailed anatomy of the area has not been properly reconstructed. This is what they were able to do with a 3D model of opening the orifice, which was used for defecation, urination, intercourse and childbirth.

The The New York Times Note that the word “cloaca” is derived from the Latin word for “sewage,” and it is not at all unique to dinosaurs: some birds, reptiles, modern amphibians, and a few mammals have one, but according to researchers’ knowledge, a cloaca is preserved in any other dinosaur fossil Non-birds. So how does this amount to those we know? It’s definitely in a class of its own, but it’s very similar to the ones seen in alligators and alligators. While most openings or openings have openings, they appear as slits or openings, as openings Psittacosaurus It has “separate side lips, but they only converge at the front, giving the mantle a unique V-shaped anatomy,” according to the study. Those lips were heavily pigmented, indicating that it might have a pointing function, and possibly a sexual function; It is also possible that they have musk glands. (Read more discoveries stories.)
