Fossil Hunting in Iowa. April, 2013. Brachiopods and Horned Coral.

I pulled more horned coral out of this creek bed in 30 minutes than I have over the course of the entire 2012 fossil hunting season.  Thank you rain.  If it wasn't for you all of these fossils would have been hidden under stagnant dirt and sand for many years.

As you can see, I found a helluva lot of horned coral.  I'm not sure of their various taxonomies but there appear to be three different variations.  I base this off of size, segments, and the appearance of the outside and inside of each specimen (bumpy, smooth, varied?).  But, damn, I'm not a geologist so I'll leave the tedium to those paid poorly for it (always end with a preposition).

As for the brachiopods, there appear to be several of those as well. I believe I have four or five variations. Not to mention a nice piece of branched coral (hanging out above the penny in the bottom photograph). 

As always, happy huntings.  I hope you find something good today.

Fossil Hunting in Iowa. Various horned coral and branch coral.

Left to Right and top to bottom.

1.  A branched coral fossil.  I happened to see it on the bank of the creek while I was falling down a hill.  I'm glad I fell down that hill, I wouldn't have been on the proper level to see it otherwise.  Serendipitous.

2. (top) This horned coral is twice as big as the ones I usually find.  This leads me to believe it's a different variation of the horned coral.  I can't seem to figure out which kind, though.  It's frustrating.  I think it may be a cystiphyllum vesiculosum" because they're common around my area...but this one is WAY too small to be that.  Sigh. Back to the drawing board.

3.  Now this horn coral can be identified!  Ha-zah! It is a "Zaphrentis" pallaensis.  It's known for it's spiny sides and, as you can see in the photo, it has those spiny sides.  Finally, I feel whole again.
