Suskityrannus ( Turonium , before 92 mya) is a representative of the Tyrannosauroidea from North America, of which very few fossils are available from this period, as the high rise in sea levels and other environmental conditions made it difficult to preserve remains from this period. The only known species is Suskityrannus hazelae .
meaning
Suskityrannus is a so-called "Missing Link" (connecting link) between the oldest representatives of the tyrannosauroids . B. also Proceratosaurus counts, and the last representatives of the family Tyrannosauridae , which developed from this superfamily, which also includes the well-known Tyrannosaurus , which is also the genus that gives this clade its name .
features
Suskityrannus was a small carnivorous theropod that was only about 2.70 m tall, but this genus still has some of the main features of later tyrannosaurids, such as the phylogenetically earliest record of an arctometatarsal foot structure of a tyrannosauroid .
Discovery story
A skull of the small theropod was discovered in 1997, and in 1998 an almost complete skeleton followed not far from the first site in New Mexico .
