Rhabdoderma Scale ID

Recommended Posts

Northernfellsfossils

I have a fish scale from the Pennine Middle Coal Measures Formation from North Cumbria (Cumberland Coalfield), UK.

Found in the local stream, where there have only ever been 4 fish found, I have found all of them- Rhabdoderma, Rhizodopsis, Megalichthys & Platysomus. 

Attached is a photo of a scale; that I think is from Rhabdoderma.

(The width of the scale is around 5mm [width as in from across from bottom left to top right of scale] 

 

Does anyone have any idea about taking this identification further- perhaps down to a species level?

Thanks,

Tom

Welcome to the forum, @Northernfellsfossils. Sounds like you are a fish finder and good spotting for that scale.

I hope someone here will help with ID, as I cannot. Good luck.

@Innocentx Thankyou! I'm a geology student living on the Coal Measures, and have started to get into fish fossils- I have a rather large collection of scales and plates as well as a few nice teeth. Hoping to learn some more via the forum!

If you click again on this FF picture posted, you should see your Rhabdoderma scale "fingerprint" pattern. This one is from the Linton Cannel Coal, USA.IMG_1182.JPG

Thankyou @fossilcrazy .... some nice photos there, especially the two individual scales. 

and thanks @ckmerlin for the paper, looking at the scale diagrams I would concur with R. elegans.
