Gryphoceratops, smallest leptoceratopsid

The interesting stuff: Gryphognathus (either hook-jaw or griffin-jaw) is seemingly the oldest (over 83 million years) and smallest (1 meter long) ceratopsian found thus far in North America as well as the smallest leptoceratopsid.

For some reason, Wikipedia states that Gryphognathus was the smallest leptoceratopsid, whereas Leptoceratops (at around 2 meters long) was the largest. However, Udanoceratops (an Asian leptoceratopsid) would have been much larger, at 4 meters long:



I won`t be surprised when leptoceratopsids smaller than Gryphognathus and larger than Udanoceratops are found, tho :cool:
