The entry on Criosphinx has not what I'd call an "error" in it... but it does go a little far afield of the origin of the name. Of course, it's a Sphinx because of the riddling, and the story with oedipus is spot-on. But the bit about crio meaning "I create" is not relevent.
The Criosphinx in Egyptian mythology is simply a ram-headed sphinx (the classic Sphinx, such as the one at Giza, are human-headed). Criosphinxes are associated with the Egyptian god Amun, and are most famously depicted in a row of sphinx statues guarding the route between Luxor Temple and Karnak.
The Crio- in Criosphinx comes from Greek -- Krios means Ram.
