This is tangential to the current discussion, but there is a
possibility that the fragmentary Early Cretaceous dicynodont described
by Thulborn & Turner (2003) is actually a sebecosuchian crocodyliform.
Agnolin &c (2010; DOI: 10.1080/14772011003594870) noted "striking"
craniodental similarities between this unnamed specimen (the "Alderley
dicynodont") and certain baurusuchids (e.g. _Baurusuchus pachecoi_),
although they don't go so far as formally overturning the original
identification.
