Their results, coupled with fossils from Spinosaurus that showed it also lived further inland along rivers and lakes, suggest it was a semi-aquatic, ambush piscivore that preferred waterside environments both along the coasts and further inland along rivers and lakes. Simultaneously, they suggested that the large tail fin was probably utilized ...
The genus Spinosaurus, from which the family, one of its subfamilies (Spinosaurinae) and tribes (Spinosaurini) borrow their names, is the longest known terrestrial predator from the fossil record, with an estimated length of up to 14 meters (46 ft) and body mass of up to 7.4 metric tons (8.2 short tons) (similar to the weight of an African ...
Its only known fossils were found in 1999 on Cajual Island in the rocks of the Alcântara Formation, which is known for its abundance of fragmentary, isolated fossil specimens. The remains of Oxalaia were described in 2011 by Brazilian palaeontologist Alexander Kellner and colleagues, who assigned the specimens to a new genus containing one ...
The newest addition to the Field Museum on Chicago's lakefront will give visitors a glimpse of the largest predatory dinosaur yet discovered via a 46-foot (14.02 meter) cast of a Spinosaurus ...
Sereno and colleagues pointed out that the more retracted nostrils in Irritator and the tall sail of Spinosaurus could also be unique traits of spinosaurines, though material from other taxa is needed to know for sure. [1] As with Suchomimus, the claw of Baryonyx had been the first discovered fossil of the animal.
Irritator is a genus of spinosaurid dinosaur that lived in what is now Brazil during the Albian stage of the Early Cretaceous Period, about 113 to 110 million years ago.It is known from a nearly complete skull found in the Romualdo Formation of the Araripe Basin.
Millions of prehistoric marine fossils were discovered beneath a California high school over the course of a multi-year construction project. The relics recovered at San Pedro High School included ...
