Blastoids are a cool fossil to find and previously I thought they only could be found in Carboniferous aged rocks. It wasn't until I visited Arkona and spoke with local expert Joe K. (Crinus on the Fossil Forum) that I found out otherwise. During my visit to Arkona last fall I got lucky and found the below specimen of
Hyperoblastus reimanni filosa.
The Blastoids from Arkona are very small and must be found while crawling on the ground or by getting lucky and screening the fossil gravels formed from the weathered rock of the formations. I found this at the base of a slope along the Ausable river in an area of washout gravel that had eroded from the Arkona formation.
That's a very cool blastoid Dave! I don't have any of those in my collection yet so keep your eyes peeled when you're at Hungry Hollow!

Dan,
ReplyDeleteYes, it's like a miniature Penetremites and very cool. I'm going to have to spend more time in the Arkona layers on my next visit so I can hopefully find more cool stuff.
