Scientists stoked to find a dinosaur's "perfect" butthole

At long last, the world has discovered the first preserved dinosaur asshole and, friends, we couldn’t be happier to share that it’s both “unique” and “perfect.” This scientific breakthrough was covered in an article from Live Science published yesterday, providing a look deep into the dino anuses previously hidden between the scaly buttcheeks of prehistory.
Just underneath a sub-heading that reads, simply, “This was a multipurpose hole,” the article goes on to explain that the discovery of a well preserved Psittacosaurus specimen that’s “scientifically known as a cloacal vent” has allowed paleontologists a better understanding of how dinosaurs laid eggs, banged, peed, and shit. Apparently the ancient butthole (which included the “remnants of two small bulges” that are probably scent glands used to blast ass gas at mates) is most similar to a crocodile’s. But, as paleobiologist Jakob Vinter says, it’s ultimately “it’s own cloaca, shaped in its perfect, unique way.”
An included illustration shows us “how the dinosaur Psittacosaurus may have used its cloacal vent (a.k.a. butthole) for signaling during courtship.” The image, in short, shows one dinosaur eagerly inspecting another’s ass with an unknowable expression—of intense curiosity, surprise, or, dare we say, desire—on its beaky dinosaur face.
The article has made some envious of Vinter’s glowing review of the rare butthole, while others have wondered about the criteria used to make this judgment.
