hollow ribs? pterosaur?

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.

Really interesting piece, sorry I have no idea either.

Waiting for the experts to take a look.

Best Regards,

Cool, but look awfully straight to be ribs..

 

You're thinking phalangi then?

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.

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.

what's the scale? some fish ribs and fin spines are hollow like this.

it’s about 3” corner to corner

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.

This is my find, I think they're ribs. Look at the texture of the bone that runs underneath. Weird piece eitherway.

The hollow appearance of the ribs could be due to the acid preparation.

What about ichthyosaur gastralia?

Didn't you find something similar in one of your hunts on YouTube? I don't quite remember which video though. But there you defined them as fish ribs... As I still don't quite know how to tell fish from reptile bone without seeing the shape if the entire bone, I'd have to base myself on the expertise of others like yourself to determine the likelihood of this being fish or not.

 

However, if you say that the hollow appearance of the ribs could be due to acid preparation, do you mean to say that they were not hollow when you found them? Is it reasonable to assume that acid would have etched away the bone, but only from the inside? Still sound to me then like there would've been matrix inside the "ribs", rather than bone. In which case the fossils were hollow to begin with? Or am I seeing this wrongly?

Here's some pictures that I took before acid prep.

I didnt do the preparation myself.

Gyrosteous fish bone is completly different from marine reptile bone.

It is usually either thin flaky bits, or the fin parts. I have lots of examples I can show to compare.
