Latenivenatrix (meaning "hiding hunter") is a genus of troodontid known from one species, L. mcmasterae, described in 2017 from remains formerly identified as Troodon. With an estimated skull length of 45 centimetres (18 in) and a full body length of 3–3.5 metres (9.8–11.5 ft), Latenivenatrix is among the largest known troodontids.[1]
Paleobiology
Paleopathology
A parietal bone catalogued as TMP 79.8.1 bears a "pathological aperture". In 1985 Phil Currie hypothesized that this aperture was caused by a cyst, but in 1999 Tanke and Rothschild interpreted it as a possible bite wound. One hatchling specimen may have suffered from a congenital defect resulting in the front part of its jaw being twisted.[2]
