I got off work early last Friday and had about 90 minutes to kill before picking my daughter up from school. So I decided to see if I could find anything in a local nature preserve with Rowlett Creek running through it, which consists of the Austin Chalk formation. There were lots of Inoceramus clam shell fragments. One fragment that I found was over 10 inches wide, but still only a tiny fragment of what must have been an enormous clam. As I was exploring I came across this rock which I though was unusual. When I first saw it I thought someone had gotten might bored and sat there hacking away at the rock to make all the hash marks, but upon closer inspection I realized the hash marks went more than surface deep. It has to be a fossil of some kind, but I’ve never seen anything like it. The only thing I can think of is maybe it is some type of a cast of a pile of shells that were together. The marks go about 4 mm or so into the Chalk so maybe it is what is left of clam fossils and the rest of the fossils have eroded away. Do any of you know what kind of fossil this is?

I went fossil hunting today in the Duck creek formation in Grayson county Texas. I saw these while hiking down a creek and was wondering if anyone could tell me what they are. I have seen these one other place, but didn’t know what it was then either. I suppose they could be a particular rock, but I tend to think it could be from a clam or something.

Hello everyone! I'm looking to see if anyone has any thoughts on this one that I found in a Cretaceous deposit of Monmouth County, NJ. It is exactly what you would expect to see from a common drumfish (Anomoeodus phaseolus) except for the fact that it has two semi-symetrical grooves in it. I don't think they were caused by wear because of the way the enamel seems to fold in. I guess it could be pathological but wanted to see what everyone thought about it. As always, any help is greatly appreciated! -Frank Note- the 'group picture' is there for sake of comparison - they are other drumfish specimens from the same area.

Look what I found! Yeah, I know it's been a while. My nursing career really ate up my life, especially being Director of Nursing at a long term care facility. So I took a step back and took things in another direction in regards to nursing and now I have Mon- Fri off to hunt! Woohooo!!! So today I hit a little spot on private land in E Texas and I found some great belemnites. Which are pretty fantastic for being in Texas.

Kayak Expeditionary Force Enters Ammonite Country
Uncle Siphuncle posted a topic in Fossil Hunting Trips
My wife had a brilliant and tastefully haute home decor epiphany. As a result, I have been conscripted to push north in search of ammonites to be inlaid in a stone mailbox post I’ve been tasked to erect. And I had just such a source in mind, off the public radar and left fallow for a year or 2 of flood cycles. I figured there might be more than one guy needed, so I invited my good friend Barry (Creekcrawler and formerly Snakekeeper here on TFF) to partake in the festivities. Barry has hosted me on some good hunts, so it was about time I reciprocated in kind. It was the maiden voyage for his new little yak, but not so for mine, deeply scarred and patched from 20 years of incessant abuse. Enough blather. Let’s see some Morts.

It is a rare weekend I'm without family, so I got a head start by leaving work with the truck packed and making a long drive north, arriving at some potential new spots well after dark. Around 11, after several duds, I found a new site in the Mainstreet limestone that yielded a decent Coenholectypus echinoid. Later, during a crick stomp in the Fort Worth formation, I got the jump on 9 Mortoniceras ammonites from 1.5 to 14 inches between 2 and 3 am. Time for 2 1/2 hours of sleep in the back of the truck...I’m guiding a buddy in the morning. Hoping for a fun and fortuitous outing.

Tylosaurus proriger Found in the North Sulphur River, Ozan Formation Dated Campanian Stage of Cretaceous (≈80 mya) Measures 4.4 cm (1.7 inches) -
So yesterday I hit the Waco Pit since it had been a couple of months since I last got out. Previous two trips were great since all I found were shark teeth. On one trip I found nine teeth in about 1 1/2 hours. Yesterday was just a chance to get outside and away from people. My other option was to go cycling on the river walk in town. Yesterday was pretty cool, temp was 47 degrees when I arrived. There was a cold breeze coming from the south. Skies were very overcast as well. Typical Central Texas weather. I hit the trail head and decided to head east inside of my normal west route. I have searched the east side a little before in the past. It's not as abundant with fossils like the other direction is but I have had some good luck finding things unusual. For instance my first summer there I found a nice rock with a Hemiaster Calvini in it. Upon getting home and cleaning away the matrix I found not one echnoid but three. So this time I wasn't expecting much. Pretty soon I found what looks like a piece of crab claw. I put that away for later. Then I find two shark teeth a few feet part. Not squalicorax but I'll take it. Finally I reach the embankments that are fun to get to and usually have tons of shells there. I find a couple of hash plates that look nice. They would both look great on a desk if I had a desk. One had a cute little echnoid spine in it. Then... I see a grey thing in the soil with spikes. At first I thought it was leaf but no this was solid. I took a few pictures of it in situ before prying it out of the ground. It looked like a horseshoe crab but I have never heard of one being found here. I looked it over several times, broke away some matrix and yes that is what it looks like. I carefully put it away in a container so I get a better look at it at home. I continue on searching for a bit. I spent a couple of hours there before heading home. At least it was a fun trip and there wasn't anyone there. I can be really anti-social at times. I get home and place the fossils in a bowl with water. After awhile I start brushing them off. What I thought was a cool looking horseshoe crab ended up being a piece of a very large Mariella piece. I'm not an expert in determining how big something is from a smaller piece but I guesstimate it could be 24 inches circumference. I'll include more pictures if it will let me.
