A disappointing trip to Ohio? Let's reconsider

Recommended Posts

A few weeks ago I complained about a fossil trip that ended with few finds. But after washing the fossils and examining them closely, I actually had a few interesting specimens. The first are these trilobites -- tiny -- but trilobites, nonetheless. The trip was in Paulding, Ohio, Devonian silica shale. trilos.jpg.392f7edd2e9222a85be347b6cfb7466f.jpg

Now, don't you feel silly for complaining?:D

I like Trilo-butts and I cannot lie.

Sure, I feel silly. Especially with this find of two specimens of Heteroschisma latum blastoids.

You should be ashamed of yourself!

It's hard to have a bad day at Paulding :)  Nice finds!

 

The two that you have as blastoids look a bit more like rugose corals to me.  Let's see what others say.

I was going to say something about that, but it is a fuzzy picture and not being familiar with the area...

They didnt look like blastoids to me.

I definitely +1 on rugose. I think that they are very worn and are missing the theca and you are seeing the septa as those vertical striations. I’ve found several such pieces myself and they are pretty neat looking up close.

I agree, those are worn Horn corals, not Blastoids. Blastoids have 5 part symmetry and are not curved whereas the specimens you posted pics of appear to have a slight curve to them. 

 

This is a pic of a Heteroschisma from Crinus' website:  http://www.crinus.info/echinoderm/data/het.htm

 

And this is one that I found: http://viewsofthemahantango.blogspot.com/2012/10/heteroschisma-canadensis-from-hungry.html

 

Maybe you are thinking of Heterophrentis sp. which is a rugose coral?
