I turned this fossil up in the garden over the weekend. It looks like a vegetative fossil rather than animal. It seems to be built up of six sided cells in rows towards a pointed end (damaged to one side). It looks as though it fractured when it was first laid down since the cellular structure appears on the surface of the fracture. Is it a seed head? Any ideas on what t could be and possible age? Are there any similar and possibly more complete fossils at the NHM which we could come and see. Also any artists impressions of the original plant.
Have tried reducing but having some finger probs. Will get back to you. Bob
The attached should be better. Sorry about delay.I understand we are on an outlying part of the Reading Beds. Anyone know if this is consistent with this fossil? Bob
I'd agree it's a very nice fossil of an Echinoderm (sorry for the Australian website link but it was the best I could find!) or Sea Urchin. The plates with the central holes are where the tube feet extended through. Nice find!
its definately a Echinoderm as has been mentioned, it looks to be fossilised in flint, that makes me think its most likely from the chalk originaly and may have been in some gravel that was put in your garden in the past, a bit of looking at chalk echinodarms has pointed out Conulus albogalerus?
(not the best image on earthlab) but it looks the right shape, but you would need an expert to confirm this
hope that helps
Jam, Thanks for that. Certainly begins to look like our fossil. The arrangement of the little hairs is a little different and I intend sketching it up when I get a chance. The two sites you gave a link to are quite impressive. This is an agricultural site with the top layer of the Chiltern chalk only a few feet down. The fossil certainly looks flinty and there are many large flints around us in the neighbouring fields. Hope to go off to NHM with the grandchildren at half term to see if we can spot similar exhibits. Bob
