@steve: Yes, "Scorpi" is on Hans' Paleobotany Pages website. I don't know whether you read the paper before of course, but now you can any way (it was a direct link to the pdf)

Joe... Do you reckon this could be a juvenile crab headshield moult?... I read the modern version can moult upto 4 times a year until it reaches maturity...or potentially a seed that hasnt fractured... westphalian... 4mm across Attachments:

Yep, horsehoe crab would be my bet, and I'd go for Euproops rather than Bellinurus, but I don't honestly know the ontogenetic sequence for these.

Joe.... Thanks... Id put euproops crab on the label... but at 4 mm it was one of them 'undecided fossils' due to its size...

I tackled a small crab headshield that I had, I thought I would give it a tickle to see if it was worthy of the collection...The body is covered in possibly kaolnite clay although or I have also heard that it could potentially also be barite (which is a main constituent in rat poison)...It doesnt want to come off anyway with a toothbrush and water so its possibly an air abrasive job to reveal a few more details in the future... The telson doesnt appear to be there and if it is it could be folded down in the nodule... I dont really want to dig a big hole just to find out and spoil the overall asthetics of the fossil...

Steve would you consider pulsing an ultrasonic cleaner to 3 sec duration interval to remove the dirt and debris.... I used this method to clean clays from specimens that come out of Arkona. PL

Peter... I'm not convinced that would work, I may be wrong i havent used one... The remains of the critter are very thin in section and the nodule siderite rock is quite strong... If there isnt a seperation layer over the fossil it is a struggle with this stuff and difficult to get the rock off...

Do you think this could be a Euproops moult?... I know theres not much recognisable there so its just a hunch but its been a very sparse species at this exposure if it is...this would be the 3rd in 3 years if it is... Attachments:
