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