THEROPODS WITH TWISTED CARINAE



Does anyone know of any theropod with teeth where one 
carina twists at its base towards the labial side while the 
other twists at its base towards the lingual side?

Please: no essays on dromaeosaurine teeth.

Also, anyone know of any recent accounts of tooth wear in 
non-tyrannosaurid theropods, excluding Fiorillo's 
observations on evidence for tooth-bone contact in the fossil 
record? I am not after references by Barrett, Upchurch and 
Fiorillo on ornithischians and sauropodomorphs.

Thanks!
