The Micro World Of The Hornerstown Formation Of Nj


Just Bob

Recommended Posts

I had some free time to go through one of my buckets of the Hornerstown Formation.

This is what I found.

First the shark teeth. Now there were not a lot of compleat teeth but there were a ton of broken shards of shark teeth. Anywhere from 100-200 shards.

Some Enchodus teeth

Now this was the best find of the bucket. A micro Enchodus fish jaw. Edit: This may not be an Edchodus jaw, fact is it is impossible to get a 100% ID. I was however told that Enchodus is a very likely possibility.

One of the more abundant fossils to my surprise were spines. I was also surprised with how well a lot of them were preserved. There were 18 pieces of tail spines in all.

Here are some of the other kind of spines I found.

Very nice. I really enjoy micro's Bob, have an extensive collection of them. That fish jaw is amazing, great find! I have been going through a bucket of Lee Creek material the last few days, taking pics and getting ready to post.

Nice micros Bob!

Thank you everyone. I just happen to find another jaw today. I guess they are more common at this spot. I know the fish spines are fairly common there. If I can I will try to get a better picture of the jaw.

I also put a turd in for your enjoyment. :D

Great micro fossils....I love the last posted picture of the jaw.....What is the location of these fossils....I have not collected much if any from the Hornerstown formation. Can you tell us were you found them...I would sure love to do some collecting there.

Great photos of your finds. That first tiny tooth is a killer. Well, a little killer, but still a killer. There is something about the really small side-cusped specimen that fascinate me. Maybe it is that I can hardly see the cusps until I use magnification ;)

Hi Bob

I'm a New Jersey digger myself, and dig the horners and Vincentown formations regularly. I know all too

well the amount of work and effort is required to pull teeth and bone out of the green ground. Just wanted to say you got some neat finds there.
