酷東西

趣味知識

Epichirostenotes is known from an incomplete skeleton found in 1923 in the Horseshoe Canyon Formation of Alberta.1

Its inner ear had a twisted common crus and an expanded anterior semicircular canal, which may have helped with balance.1

The name Epichirostenotes means 'above Chirostenotes' because it lived later than its relative Chirostenotes.1

This dinosaur belongs to the family Caenagnathidae, which are oviraptorosaurs that had toothless beaks and often crests on their heads.1 4

Epichirostenotes lived about 72 million years ago during the Late Cretaceous period.1

The only species in this genus is Epichirostenotes curriei, named in 2011 by Sullivan, Jasinski, and van Tomme.1 4

發現: The first skeleton of Epichirostenotes was found in 1923 in Alberta, Canada. It was originally thought to be a different dinosaur called Chirostenotes pergracilis, but in 2011 scientists Sullivan, Jasinski, and van Tomme gave it its own name, Epichirostenotes curriei.1
仍有爭議: Scientists are not sure exactly how big Epichirostenotes was, because only a partial skeleton has been found.1
