Latest Prosauropoda Stories
Attempts to identify the oldest known dinosaur embryos have resulted in some stunning new discoveries about the early development of the ancient creatures, according to a new study published this week in the Journal of Vertebrate Paleontology.The dinosaur eggs in question, which were discovered in Cape Town, South African back in 1976, came from the species Massospondylus, a predecessor of plant-eating sauropods such as the Brontosaurus, according to BBC News Science Reporter Katia...
Scientists have discovered in China the first complete skeleton of a pivotal ancestor of Earth's largest land animals "“ the sauropod dinosaurs. The new species, tentatively dubbed Yizhousaurus sunae, lived on the flood plains around Lufeng in the Yunnan Province of South China about 200 million years ago. The species helps explain how the iconic four-footed, long-necked sauropod dinosaurs evolved.Unlike the 120-foot-long, 100-ton sauropod giants that came later, Yizhousaurus was about 30...
(Corrects affiliation of paleontologist in sixth paragraph) By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Unhatched dinosaur eggs dating back 190 million years carried fully developed embryos that would have been born clumsy and helpless, scientists said on Thursday. Their finding, published in Friday's issue of the journal Science, suggests even the earliest dinosaurs tended carefully to their young. It also raises questions about how the giant four-legged...

RIO DE JANEIRO, Brazil (AP) -- Scientists have unveiled a replica of a new species of dinosaur whose fossils were recently discovered in Brazil. The new dinosaur, an ancestor of the brontosaurus, has more in common with species found in Europe than with other finds in South America.A replica of Unaysaurus Toletinoi, a small plant-eater that lived some 230 million years ago, was unveiled last week at the National Museum in Rio."It differs from all other dinosaurs," Zootaxa, a...

Massospondylus, meaning “longer vertebrae,” is a genus of prosauropod dinosaur from the Hettangian to Pliensbachian ages of the Early Jurassic Period (200 to 183 million years ago). Massospondylus was discovered in 1853 by J.M. Orpen in the Upper Elliott Formation at Harrismith, South Africa. It was described in 1854 by Sir Richard Owen. It is one of the first dinosaurs to have been named. The type species is M. carinatus. There have been seven other named species during the past 150...
Plateosaurus, meaning “Broadway lizard,” is a genus of plateosaurid dinosaur from the Late Triassic Period (216 to 199 million years ago), which lived in what is now Central and Northern Europe. It is a primitive sauropodomorph dinosaur. There are two recognized species: the type species P. engelhardti from the late Norian and Rhaetian stages, and the slightly earlier P. gracilis from the lower Norian. Plateosaurus was discovered in 1834 by Johann Friedrich Engelhardt and described...
Yunnanosaurus, meaning "Yunnan lizard," is a genus of prosauropod dinosaur from the Early to Mid Jurassic Period. This was perhaps one of the last living prosauropods of the time. It was discovered by Yang Zhongjian in the Lufeng Formation of Yunnan, China. The find consisted of twenty incomplete skeletons, including two skulls, and were excavated by Tsun Yi Wang. The type species, Y huangi, was named by C.C. Young in 1942, and created the family Yunnanosauridae based on the findings as a...
Thecodontosaurus, meaning "socket-tooth lizard," is a genus of sauropodomorph dinosaur from the Norian or Rhaetian age of the Late Triassic Period. Known mainly from "fissure fillings" found in South England and Wales, the original remains were destroyed by the Germans during World War II bombings. However, more fossils have been found at a number of different sites. Some of the new material collected is of a juvenile specimen that may belong to the species, T. caducus, described by Adam...
Adeopapposaurus, meaning "far eating lizard", is a genus of prosauropod dinosaur from the Early Jurassic Period. It was found in the Cañón del Colorado Formation of San Juan, Argentina. It was described in 2009 by Ricardo N. MartÃnez. The type species, A. mognai, is named for the location where it was found. Adeopapposaurus is known from four partial skeletons and two partial skulls. The form of the bones at the tips of the jaws suggests that it had keratinous (horny) beaks. The...
