hollow ribs? pterosaur?


Recommended Posts

Hi there, I’d like to get the expert opinion of you all. Could these be pterosaur ribs? i just know they’re from Whitney, Yorkshire. As you can see, they’re hollow, and all I know of, that would have little hollow ribs like that are pterosaurs, and avian dinosaurs, but I'd imagine it was very uncommon for articulated ribs from a raptor to make it to, and “survive” an aquatic deposit, intact and untouched, although I know pterosaur bones are sometimes found in aquatic fossil deposits, at least from coastal areas. I'm not sure what else would be found there with hollow ribs, and these also seem like maybe they’re too long for ribs of that size/width, so I'm at a total loss now, and wanted to ask for help in figuring out what these could be from.

 

I'm also interested in what the large flat bone might be, and any others too, of course, if anyone can recognize what it/they might be.

No idea but not thinking pterosaur.  Plant?

I would be hesitant to ID almost anything with photos at this resolution and clarity...much less purchase it.

too perfectly round to be ribs, methinks.

Unfortunately, I wouldnt consider myself knowing enough about pterosaur bones to be much help.

 

Pterosaurs have been found at Whitby though. Parasipcephalus, it is a very small species. But not much info on it.

thank you, that’s a better way to put it than “too long”.

do all, or most pterosaurs have the same number of ribs? i can’t find any info on the number any species have, but looking at diagrams and skeletons, it seems to be somewhere around 12-15. i figured maybe that could rule out ribs if the numbers didn’t match up, but the numbers don’t appear to help.

Are you able to provide better focused images?

Yeah  :/  but I do feel like it can be confidently accepted that they’re not pterosaur ribs, though.
