Fossil collection complete already?

So, I donated the Sabertooth body to Blathers this morning, and he told me the fossil collection is complete (minibrag) but according to the list on Gamewith, I'm still missing the Ichthyosaur skull and torso? I can't imagine Blathers being a fibber (otherwise it's a slingshot full of stinkbugs for him) so is this a miscount on the Gamewith side, or are there more fossils than there is museum space?
