A Tyrannosaurus rex skull. The find consisted of 47 bones (two missing) and 35 loose teeth, mostly loosely associated in soft matrix, with a fused braincase. The loose association of the cranial bones may be consistent with cartilaginous symphyses as is found in the jaws of theropods and may imply T. rex could swallow larger prey or pieces than the resting gape would suggest. It's the second largest Tyrannosaurus skull found and probably the best preserved.

AMNH 5027
A Tyrannosaurus rex skull that was the premier specimen until Stan showed up. It was discovered by Henry Fairfield Osborn, who named it in 1905.A cast of this specimen may be seen in many of the major museumsaround the world (e.g. Graves Museum). When looking "eyeballs to eyeballs" (i.e. frontally), the skull is lopsided having been deformed by the overburden. The hard stone matrix presented difficultiesin restoration. The original specimen is in the New York American Museum of Natural History.

Gorgosaurus (fierce lizard) A 76 million year old Albertosaur, skull still in matrix, found in the Two Medicine Formation, upper Cretaceous (Campanian, 83- 75 mya.), Montana near Glacial National Park. Several Maiasaura and Bambiraptor fossils were located nearby. It has approximately 60 4 to 5 inch teeth, was about 9 feet tall and weighed about 4000 pounds being 25 to 30 feet long.

Tinker, a juvenile Tyrannosaurus rex nicknamed after one of the discovery team,Ron "Tinker" Frithiof, the specimen was discovered by Kim Hollrah with Michael Harrell when the claws were located in a ravine near Houston, Texas. The specimen appears to be between 70 and 90 percent complete. (A work in progress.) Tinker has his own web site:
