Lesser-Known Running Lizards (minor update at the end)

by Jaime Headden, from Wikipedia

In the last post, I briefly mentioned a group of dromaeosaurs called unenlagiines. This is still a rather obscure group, especially to the general public, so I wanted to give these South American dromaeosaurs some much-deserved time in the spotlight.

This is a small group—only three (but possibly four or five) genera have been named. They are atypical dromaeosaurs for a number of reasons, foremost among them the elongate, narrow snout packed with minute teeth which lack serrations. While most appear to have been small, one of them was one of the largest dromaeosaurs, approaching Achillobater and Utahraptor in terms of overall size.
