tmaier Posted August 19, 2014 Share Posted August 19, 2014 It's hard to tell under that layer of limestone or bryozoa. I think you have to find a safe way to expose a bit of what is under it to see some diagnostic features. Otherwise, it's like playing "what's under the blanket?"

tmaier Posted August 19, 2014 Share Posted August 19, 2014 I would poke it a bit with an exacto knife and see if it crumbles away. Don't try to do the whole fossil yet, you just want to take a peek to see if there is the sign of a test under it. A test is the skeleton. A sea urchin will have plates and other features. Then if you find that it is a seaurchin, you would amke plans to remove the whole thing. Link to comment Share on other sites More sharing options...
DE&i Posted August 19, 2014 Author Share Posted August 19, 2014 (edited) Ok im up for the challenge the whitish coating seems very durable im not sure if there would be any crumbling properties to it. Ill report back hear with my progress thank you for getting me started. Regards, Darren.

tmaier Posted August 19, 2014 Share Posted August 19, 2014 When I work a site, I always pick up some scrap pieces to test their characteristics for how to work the matrix. It's not good to learn the properties of the matrix with your valuable specimen. Do you have any pieces you don't like? Link to comment Share on other sites More sharing options...

Do you have any pieces you don't like?Good call....I can see the sense in that, unfortunately if this piece is deemed some sort of Echinoidea it would be a rarity from this particular location.Especially as its a glacial till eratic I can't find any reference of such a find.This is the first find with such an appearance that I've found for a few years and I've looked relentlessly . But to no avail, haven't found anything with the slightest resemblance. Regards, Darren.

Kosmoceras Posted August 27, 2014 Share Posted August 27, 2014 Don’t think so Darren; can’t really see any evidence of plates. I don’t think it will prep either. On the other hand, the shape is very suggestive, and I have found echinoids which are fairly alike (as in not much surface detail) on the southern Swedish coastline.
