This weeks #Lego #FossilFriday is #Ornithomimus.

In 1890, Ornithomimus velox was given a type species by O. C. Marsh. It was based off a partial hindlimb, and forelimb that had been found in 1889 by George Lyman Cannon.

He also named two other species O. tenuis, and O. grandis. Both are fragmentary, and now believed to be tyrannosauroid material.

In 1892, O. minutus was named by him as well. It's now thought to be alveresaurid material.
