Elaphrosaurus, an ornithomimid dinosaur from the upper jurassic of north America and Africa

  • Peter M. Galton
Article

Abstract

A humerus from the Morrison Formation (Upper Jurassic) of western North America is referred toElaphrosaurus which is represented by a skeleton from the Tendaguru Beds of Tanzania, East Africa. The referral ofCoelurus agilis Marsh (Morrison Formation, western U.S.A.) andTeinurosaurus sauvagei (Huene) (Kimmeridgian, France) toElaphrosaurus is incorrect. The recognition ofElaphrosaurus from North America provides additional evidence for a Morrison-Tendaguru land connection sometime during the Late Jurassic.Elaphrosaurus is referred to the family Ornithomimidae because the form of the humerus, slender and straight with a low deltopectoral crest, is diagnostic of this family.Deinocheirus from the Upper Cretaceous of Mongolia is a giant ornithomimid.

Kurzfassung

Ein Humerus aus der oberjurassischen Morrison-Formation des westlichen Nordamerika wird zuElaphrosaurus gestellt, der durch ein Skelett aus den Tendaguru-Schichten von Tanzania in Ostafrika bekannt ist. Die Zuweisung vonCoelurus agilis Marsh aus der Morrison-Formation und vonTeinurosaurus sauvagei (Huene) aus dem französischen Kimméridgien ist nicht richtig. Der Nachweis vonElaphrosaurus in Nordamerika liefert ein weiteres Zeugnis einer Morrison-Tendaguru-Landverbindung in der spaten Jurazeit.Elaphrosaurus läßt sich den Ornithomimidae zuordnen, für die der schlanke und gestreckte, mit niedrigem Deltopectoralkamm versehene Humerus charakteristisch ist.Deinocheirus aus der Oberkreide der Mongolei ist ein riesiger Ornithomimide.
