Carnotaurus Scaly Skin

Paleontologists have described in detail for the first time the scaly skin of Carnotaurus sastrei, an abelisaurid theropod that lived in South America during the Late Cretaceous epoch, sometime between 72 and 70 million years ago. An artist’s reconstruction of Carnotaurus sastrei based on the scaly skin described by Hendrickx …

Non Avian Dinosaur

Although paleontologists know now much about dinosaurs and their appearance, they have not known anything about how their cloacal region — the all-purpose opening used for defecation, urination and breeding — appears. Paleontologists from the United Kingdom and the United States have now described the cloacal opening of Psittacosaurus, an …

Evolutionary Link

Paleontologists have described the first three-dimensional preservation of soft tissue in Namacalathus hermanastes, a skeletal metazoan (multicellular animal) that lived some 547 million years ago (Ediacaran period) in what is now Namibia, and established a strong evolutionary link between Ediacaran and early Cambrian metazoans. Namacalathus (individuals numbered). Centimeter scale. Image …
