Talk:Timeline of ankylosaur research

Metatetrapous
It seems like every source I read on whether or not Haubold considered Metratetrapous ankylosaurian is kind of contradictory and I don't have access to Haubold 1971 to verify. Be aware that it may have been seen as ankylosaurian from the beginning instead of just referred in 2001. Abyssal (talk) 15:29, 23 July 2015 (UTC)

Possible Alaska ankylosaur footprints
Gangloff may have reported ankylosaur footprints from Alaska back in 1998, although McCrea, Lockley and Meyer 2001 are a bit vague on whether or not Gangloff himself recognized it at the time. I'm not sure which paper they cited as its not listed in the'r references it is probably
