Fossil found at Saltburn beach

[Eloise]

Hi all,

 

I posted yesterday about an interesting rock found at Saltburn Beach and was informed it was crinoid stem sections. I also found this rock on the same day which appears to have some fossils in it? I’m wondering if these are also from Crinoids? They are only visible when the rock is wet. 

 

Thanks!

I would say these are indicative of coral.

Not crinoids, but these look to be remains of the corallites of a rugose coral colony. Nice find! If you add information like pictures of the cross sections, and the locality found in, a more precise ID will be possible.

See the title and her first post. Saltburn is in Yorkshire near Whitby. Probably another Carboniferous erratic.

Indeed; a Lower Carboniderous erratic containing what would appear to be a phaceloid tabulate coral, probably a syringoporid.

tabulate Coral

I have similar from Devonian rocks in Michigan

It reminds me more of a fasciculate rugose rather than a syringoporid, mainly based on the cross sections showing internal structure, though close up photos of the most detailed cross sections would be able to convince me yea or nay.

It's a Siphonodendron (a Carboniferous rugose coral), clearly shown by the septa and the clear central columella.  (Superficially similar to the tabulate Syringopora which internally only has funnel shaped tabulae and sometimes septal spines visible.) 
It's not quite clear enough to tell the exact species (polishing would look good  ) but there appears to be one set of dissepiments around the outer edge in which case S. pauciradiale is a possibility.

Nice! Thanks Tarquin, thought so.
