Diplodocinae

Marsh, 1884 Type genus Diplodocus

Its genera lived 154.8–132.6 million years ago Late Jurassic–Early Cretaceous
Late Jurassic and Early Cretaceous stages

Diplodocinae is a subfamily of diplodocid sauropod dinosaurs that lived from the Late Jurassic to the Early Cretaceous, roughly 161 to 136 million years ago, with fossils known from North America, Europe, Africa, and South America. Its members include Diplodocus, Barosaurus, Galeamopus, Tornieria, Supersaurus, Leinkupal, and Ardetosaurus. These are among the most gracile and elongate of the diplodocids, distinguished by especially long necks and tails built from extremely elongate cervical vertebrae and slender overall proportions.

Diagnosis

  1. Mid-cervical vertebrae extremely elongate, with elongation indices commonly exceeding four
  2. Slender, gracile cervical and dorsal proportions relative to Apatosaurinae
  3. Cervical ribs slender and not ventrally displaced
