Unknown derived fossil

[DE&i]

This is a derived fossil I picked up from the Carstone Formation (Albian stage, Early Cretaceous) which has Kimmeridge clay below. It doesn’t have the appearance of any marine reptile bone structures that I’m familiar with as that was my first thoughts

Would anyone else have any suggestions please.

That screams fish to me because of the flaky/laminated texture of the bone.

Not sure what you mean by 'derived' but it is definitely a piece of fossil bone.  I also lean towrds fish, but it is only whispering, not screaming.

I have the volume in my head turned up so I can hear over the tinnitus.

Thank you @Ptychodus04 fish sounds likely I guess

Thank you @jpc a derived fossil  would be redeposited in a sediment which is younger than the one in which it first occurred. So I would presume it could be from the Kimmeridge clay.

Ah... derived to me means evolutionarily derived... more advanced.  Usually it is used as such for indoividual characteristics.  Ex: Large brain is a derived characteristic for primates.

It’s one of the duel meaning words I suppose, hope it sounded OK

NO sweat.  Just needed clarification.  Thanks.

Derived meaning "from an older formation" is a standard geological usage, as well as the biological one.  It whispers "fish" to me too.

There's an awful lot of cancelous bone in this piece, but i can see what you guys are saying. Looks more reptilian to me (in my quietest whisper).

Thank you everyone,

 

So I ran with the fishy vote, coupled in with Kimmeridge Amiiformes, and once again the top internet searches took me to The Steve Etches collections.

I’m going with the Caturus fish, link supplied below.

That said there is a lot of other fish in his collection, I wonder what part it could be if it is indeed a fish.

This must be a British thing.  I have never heard it.  We use the word "reworked"

So might we, there's a choice.  From Wikipedia, amongst others: 

"A derived, reworked or remanié fossil is a fossil found in rock that accumulated significantly later than when the fossilized animal or plant died.[46] Reworked fossils are created by erosion exhuming (freeing) fossils from the rock formation in which they were originally deposited and their redeposition in an younger sedimentary deposit."

"remanie"(with accent aigue)... I speak French and I did not know that one.  And i know we have a member here who uses that as his name.  

 

See, ya learn something new every day.

Great photography.

Makes ID and viewing a pleasure.
