I’ve looked at many dozen Solnhofen pterosaur specimens and haven’t yet found two that are identical.
If you can present me/us with two identical Rhamphorhynchus or Pterodactylus I will make the announcement. Send in pictures or museum numbers, please.
I haven’t compared every specimen to every other one yet, but I’m not sure we can find two identical specimens. There is an incredible variety out there.
The most likely scenario would be to find two conspecific pterosaurs on the same slab, but I don’t think there is such a thing yet discovered.
