“The limestone these fossils are embedded in may be very comparable, which mixed with the truth that they had been each extracted round 1880 makes me assume they’re in all probability the identical animal. We might want to do extra analysis earlier than we’re in a position to say with any certainty.

“It is wonderful that this new fossil was sitting inside a pillar for 130 years. It might have been misplaced endlessly, so we’re very grateful to Paul Deans for recognizing it, bringing it in and donating it to the museum.”
