I too have a problem with a four toed possible theropod .... but not from the
Cretaceous. I found mine in the Middle Jurassic of Northern England.
The toes are elongate and pointed and slightly curved. At first I
thought it may have been the track of a croc or similar, but I showed
it to Bill Sargeant who said it wasn't. It remains a mystery and
undescribed. At least mine was not a segnosaur, perhaps a late
surviving prosauropod? .... perhaps there is a group of theropods
with four toes for which no ossified remains have been found???
Tracks are notoriously difficult to assign to any group unless you
find the animal that made them collapsed at the end of the trackway!
