Description

Age: 100 mya Crystal System: Hexagonal System Description: Phylum: Chordata Class: Reptilia Clade: Theropoda Family: Spinosauridae Common Name: Suchomimus Species: s. tenerenis Age: Early Cretaceous Location: Tegama Bed, Elrhaz Formation, Niger, Africa Description: This specimen is a fiberglass cast of a skull which is highly detailed and fully represented with the exception of a few missing teeth which will have to be cast at a later date. The color is a bone white. This specimen is on loan from Mike Hammer. Physical Charateristics: Suchomimus ("crocodile mimic") is a genus of large spinosaurid dinosaur with a crocodile-like mouth that lived between 121–112 million years ago, during the late Aptian stage of the Cretaceous period in Africa.[1]Unlike most giant theropods, Suchomimus had a very long, low snout and narrow jaws studded with some 100 teeth, not very sharp and curving slightly backward. The tip of the snout was enlarged and carried a "rosette" of longer teeth. The animal is reminiscent of crocodilians that eat mainly fish, such as the living gharial, a type of large crocodile with a very long, slim snout, from the region of India. Suchomimus also had a tall extension of its vertebrae which may have held up some kind of low flap, ridge or sail of skin, as seen in much more exaggerated form in Spinosaurus. Detailed study shows that the specimen of Suchomimus was a subadult about 11 meters (36 ft) in length and weighing between 2.9t and 4.8t, but scientists think that it may have grown to about 12 meters (40 ft) long, approaching the size of Tyrannosaurus. The overall impression is of a massive and powerful creature that ate fish and presumably other sorts of meat (carrion, if naught else) more than 100 million years ago, when the Sahara was a lush, swampy habitat. Elements: Two piece skull fully intact except for two unidentifiable bone fragments.
