Name: “Ornithomimus” minutus

Name Meaning: Small Bird Mimic

First Described: 1892

Described By: Marsh 

Classification: Dinosauria, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Alvarezsauria, Alvarezsauridae. Parvicursorinae 

“Ornithomimus” minutus was originally based on toe bones, and thought to be a separate species of Ornithomimus proper, hence its name. This specimen has been lost, and was also thought to be a species of Dromaeosaurus, or Troodon. It was found in the Denver Basin of Colorado, living in the Maastrichtian age of the Late Cretaceous, approximately 68 million years ago. It has since thought to be the specimen of an Alvarezsaur, with similarities in the toe bone compared to Mononykus. Still, it remains something of a mystery.
