 Burnham also offers an alternative hypothesis that a larger brain could be selected for as a result of hunting more agile prey items such as lizards and mammals.The "Bambiraptor" holotype had with 14 cm³ the largest brain for its size of any dinosaur yet discovered, although the brain size may be due to its age, because juvenile animals tend to have larger brain-to-body ratios compared to adults.During the conference where "Bambiraptor" was first introduced, the dinosaur reconstruction specialist Brian Cooley portrayed "Bambiraptor" as having feathers, despite the fact that no feathers were found with the fossil itself.
