Crocodylus thorbjarnarsoni
Crocodylus thorbjarnarsoni is an extinct species of crocodile from the Pliocene and Pleistocene of the Turkana Basin in Kenya. It is closely related to the species Crocodylus anthropophagus, which lived during the same time in Tanzania. C. thorbjarnarsoni could be the largest known true crocodile, with the largest skull found indicating a possible total length up to 7.6 m (25 ft). It may have been a predator of early hominins. The largest C. thorbjarnarsoni skull found (KNM-ER 1682) measures 85 cm (33 in) from the tip of the snout to the back of the skull table, in comparison, the largest known extant Crocodylus skull is that of a saltwater crocodile, measuring 76 cm (30 in). Based on regression analysis for Crocodylus, this corresponds to a total length of 6.2–6.5 m (20–21 ft) but such analysis have been shown to underestimate the size of very large individuals by as much as 20%, which means it could have been as long as 7.6 m (25 ft).
Gorgosaurus libratus
Gorgosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, between about 76.5 and 75 million years ago. Fossil remains have been found in the Canadian province of Alberta and possibly the U.S. state of Montana. Paleontologists recognize only the type species, G. libratus, although other species have been erroneously referred to the genus. Like most known tyrannosaurids, Gorgosaurus was a bipedal predator weighing more than a metric ton as an adult; dozens of large, sharp teeth lined its jaws, while its two-fingered forelimbs were comparatively small. Gorgosaurus was most closely related to Albertosaurus, and more distantly related to the larger Tyrannosaurus. Gorgosaurus was smaller than Tyrannosaurus or Tarbosaurus, closer in size to Albertosaurus and Daspletosaurus. Adults reached 8 to 9 m (26 to 30 ft) from snout to tail. Paleontologists have estimated full-grown adults to weigh about 2.5 tonnes (2.8 short tons), perhaps approaching 2.8–2.9 tonnes (3.1–3.2 short tons). The largest known skull measures 99 cm (39 in) long, just slightly smaller than that of Daspletosaurus.
