Professor David Bruce Weishampel is an American palaeontologist in the Center for Functional Anatomy and Evolution at Johns Hopkins University School of Medicine. Weishampel received his Ph.D. in Geology from the University of Pennsylvania in 1981. His research focuses include dinosaur systematics, European dinosaurs of the Late Cretaceous, jaw mechanics and herbivory, cladistics and heterochrony and the history of evolutionary biology. Weishampel's best known published work is The Dinosauria University of California Press; 2nd edition. He consulted for Jurassic Park and is a good friend of Steven Spielberg. He has received an Academy Scientific and Technical Award.
Chubutisaurus is a genus of dinosaur from the Early Cretaceous Period. It lived in South America. It is classified as a sauropod, specifically one of the titanosaurs. The type species, Chubutisaurus insignis, was described by del Corro in 1975. Its fossils were found in the Cerro Barcino Formation, Albian stage, about 110 million years ago. Chubutisaurus had a more robust radius than Venenosaurus. In 2010 Gregory Paul gave a length of 18 meters (59 ft) and a weight of 12 tonnes. Thomas Holtz estimated its length at 23 meters (75.5 ft) in 2012.
Microhadrosaurus is a genus of hadrosaurid dinosaur from the Campanian or Maastrichtian-age Upper Cretaceous Yuanpu Formation of Guangdong, China. Although its name identifies it as a small hadrosaur, it is based on juvenile remains, and the size of the adult hadrosaur is unknown.
