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: Ditch (creek bed) Time Adventure Time!

Found some nice Brachiopods and a killer horned coral over the weekend (top right, it's segmented and huge, totally excellent).  The ditch was full of biting flies, mosquitos, and itchy plants...if I didn't make it out with a handful of fossils I would have looked pretty pathetic.

Fossil Hunting in Iowa: Coral

Left to Right: 1. small chunk of fossilized coral or sponge 2. buffalo nickel so you can guesstimate the size of each fossil 3. Part of a fossilized buffalo tooth.  The surface is very beautiful and looks like the cracked glaze of a raku fired pot. 4. Unidentified solitary coral.  I have never seen a fossil like this one.  Below is a detail of it's center. 5. a really nice chunk of coral.  I usually find tiny pieces of this particular kind but now I finally have a charcoal briquet sized piece.  I was totally pumped to find it.  I need to get better at coral identification.

A detail of the #4 Solitary Coral.  This piece (and all of them, really) have inspired me to find out more about fossils.  I have a generalized knowledge of the stuff, in that if I see something unusual I'll pick it up.  We'll be going to a Lapidary Society Meeting in a couple weeks where I hope to extract some knowledge from the experts.

A coyote skull found on a sandbar.

A pig jawbone found on a sandbar.  I assume someone slaughtered one and threw it's remains in the river as pigs are not native to the area and do not run feral (i god I hope pigs never run feral in Iowa.  They're so destructive)

Skunk River. Fossil Hunting in Iowa.

It was an Ames, Iowa kind of a weekend.  The Skunk River runs through the town and there have been rumors of a dry river bank.  A dry river bank makes for good fossil hunting so KP, the dog, and I decided to check it out.  Lo and behold, that damn river was dry.  We counted 2 puddles in a 2 miles stretch.  There were hundreds of minnows and frogs in each patch of water.  It was an interesting microcosm if not a little crowded for the poor guys. 

Here's one of the pieces I found on the river bank.  I believe it to be a solitary coral of some sort.  It looks unlike the other solitary corals I've found in the past (see horned coral).  I know it takes a lot of pressure to make a fossil so perhaps it's just a squished horned coral.  I'm not an expert, I'm still a novice but none of my fossil books have a picture of this fossilized fellow.  If any of you know anyone I could ask that would be great.  Maybe I'll put the image on a fossil forum website later today and get back to you.

This is the back of the same solitary coral (or what I believe to be a solitary coral).  It's about the size of a dime.

Left to Right: 1. a rock that looks like a silly profile. 2. This fossil was odd, I'm not sure what it is.  If you hold a magnifying glass up to it it has a pattern like some kind of a dense coral.  Lots of circular patterns. 3. A piece of a fossilized bone (the outside). 4. A piece of a fossilized bone on the inside, you can see the marrow. 5. A piece of a fossilized tooth.  This one was a heart breaker because it would have been so awesome had it not been broken.  The enamel of the tooth looks like pottery glaze.  Sigh.  Oh, well.  At least I still found it. 6. A piece of native American pottery.  This piece was found in Marion County.
