Fossil range: Early Cretaceous

2000. According to the authors, the new genus is one of the "most complete and best preserved Cretaceous theropods described thus far from Africa." The well-preserved specimen had a long, three-fingered hand which included a partially opposable thumb (a "killer claw"). The fossil also contained gastroliths in its stomach. The specimen appeared to be a late juvenile about 9 in (22.8 cm) high and around 2.6 (0.7 m) long, making it the eleventh smallest dinosaur, though the length of its tail is not known.
