Deinosuchus hatcheri

Deinosuchus is an extinct relative of the alligator that lived 80 to 73 Ma (million years ago), during the Late Cretaceous period. The first remains were discovered in North Carolina in the 1850s, but it was not until 1909 that the genus was named and described. Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of this massive predator. Although Deinosuchus was far larger than any modern crocodile or alligator—measuring up to 12 m (40 ft) and weighing up to 8.5 metric tons (9.4 short tons)—its overall appearance was fairly similar to its smaller relatives. It had large, robust teeth that were built for crushing, and its back was covered with thick semispherical osteoderms. One study indicates that Deinosuchus may have lived for up to 50 years, growing at a similar rate to that of modern crocodilians, but maintaining this growth over a much longer period of time.

Paul Sereno2

Paul Sereno is an American paleontologist who is the discoverer of several new dinosaur species on several continents. He has conducted excavations at sites as varied as Inner Mongolia, Argentina, Morocco and Niger. He is a professor at the University of Chicago and a National Geographic "explorer-in-residence." Sereno's most widely publicized discovery is that of a nearly complete specimen of Sarcosuchus imperator (popularly known as SuperCroc) at Gadoufaoua in the Tenere desert of Niger. Other major discoveries include Eoraptor - the oldest known dinosaur fossil, Jobaria, the first good skull of Carcharodontosaurus iguidensis, Afrovenator, Suchomimus and the African pterosaur.

"It is well known, that on the Ohio, and in many parts of America further north, tusks, grinders, and skeletons of unparalleled magnitude are found in great numbers, some lying on the surface of the earth, and some a little below it ... But to whatever animal we ascribe these remains, it is certain that such a one has existed in America, and that it has been the largest of all terrestrial beings."
—U.S. President Thomas Jefferson describing the bones at Haynes cave. Notes on the State of Virginia (1782), 71, 77.

Dorudon field1

This fossil skeleton of Dorudon, around 50 million years old, has been partially excavated and reassembled where found in Wadi Al-Hitan. Dozens of whale skeletons remain undisturbed on the floor of the valley, usually indicated by small mounds created as wind erosion uncovered them. Dorudon was a genus of ancient cetacean that lived alongside Basilosaurus 41 to 33 million years ago, in the Eocene. They were about five meters (16 ft) long and were most likely carnivorous, feeding on small fish and mollusks. Dorudontines lived in warm seas around the world. Fossils have been found in North America, Egypt as well as Pakistan the eastern part of which bordered the ancient Tethys Sea.
