Hawkser Find possible Bone

Recommended Posts

I found this between Hawkser and Robin Hoods Bay near Stainsacre. Any ideas or help with identification please. I also found some nice therapod prints which I will load later. Could this be sea reptile or is it a bamboo like wood. I really hope this is bone as I managed to get cut off by the tide and having descended the steps at 10.15 am last Tuesday I got back up them at 13.13 the following day. 26 hours wet and hungry with no phone signal and no takers on my morse code SOS torch signals. Wife was not impressed.

Looks like an internal cast of a stem from a plant called Calamites.

I agree with that ID.

I think the Carboniferous - Early Permian Calamites would not fit with the Jurassic sediments of the Cleveland Basin. Geology of the Yorkshire Coast

Could be one of these : Palaeobotany and petrology of a Middle Jurassic ironstone bed at Wrack Hills, North Yorkshire

I'm leaning toward Equisetum, maybe Equisetum beanii (Bunbury) Harris, see document.

Very interesting thank you very much for sharing your knowledge. The area has a lot of leaf fossils - this one was approximately .5 mile away on the same trip along with coastal ripple impressions (I am told these are not strictly fossil). I will attach photos below.

I could interpret the strange shapes on the rocks of the last photo as diagenetic structures. The meandering forms could be Westerstetten structures, the Liesegang rings are visible on the surface of the other rock from the left side of the picture.

 

according to Adolf Seilacher. 2007. Trace Fossil Analysis.

 

" They consist of micritic calcite and cover upper surfaces of blocks of Jurassic limestone floating in the residual clay of a karst fissure. (...)
Fine internal lamination also shows that the sausages accreted at their ends. This links them with the colorful Liesegang rings that decorate the sandstone walls of Petra (Jordan). Similar patterns have been described as meandering trace fossils (cf. Helminthoida) in Triassic sandstones of Germany. "

That long plant leaf looks like Odontopertis, but then abysunder will say that can't be possible due to the age.
 

I think you are referring to Odontopteris;)
