I finally went over to a slow-moving construction site that has been in process for weeks, if not longer. With little hope due to a lot of bigger rocks being hauled off, I walked along the elevated slopes of plowed dirt and smaller rocks that remained. To my surprise, I found some nice Fort Worth formation echinoids (holaster and macraster sp) and some small ammonites of the mortoniceras sp. I also found a very well fed nautiloid, I’m nicknaming Fat Boy Lloyd (you know, respectfully like he’s a rapper). It weighed in at 5 lb 10 ounces! I thinks it’s paracymatoceras species given the visible lines that are very close together. I also found what I think is a nicely ornate trigonia clam. Tarrant county, Texas.

I found this interesting mort last September, I’ve dubbed him Spikey. This came from my previously untapped Fort Worth formation spot that had ammonites laying around, just waiting for me to clean the spot out (until more erosion occurs). First pics are before preparation, last few are after. Mercer Brugler prepared these for me.

Ideas for mortoniceras ammonites-varying condition
Shaun-DFW Fossils posted a topic in Fossil Preparation
I had a fairly good last two Saturdays finding larger (relatively for me) mortoniceras ammonites in a creek off of I-35W south of Denton, TX. Here are some unprepped stacked ones waiting in line at the beauty shop. I also found a 14-inch mortoniceras that appeared risky to remove at first glance so I left it in the surrounding matrix and removed the entire area. Very heavy quarter mile hike back to my car. But I’m stronger for it. lol! I also wanted to highlight a 13-inch ammonite I skeptically chiseled out of a huge rock in the summer of 2023 from the Benbrook area (east of the lake). The creek side exposure was so worn down, there’s almost nothing left. But the other side, once I got it out, showed a beautiful orange color. It was broken in two pieces and the end of the ammonite had some very dense rock around it. Instead of chopping it off and trying to make a smaller ammonite, we decided to carve the rock into its own base. Glue lines were prepped out and it made for a very nice one-sided display after the usual yet detailed air scribe and air abrasive work. Some people like perfection on both sides (I do too), but sometimes creative solutions exist to make the imperfect look great.- 1 reply

I went to my favorite Fort Worth formation spot near my house (Johnson County) and came home with a nice Christmas present to myself, 6 macraster echinoids, 2 of which are nearly perfect and are now amongst the best I have. They’re also huge, I am naming one Absolute Unit and the other The Rock. Also a rough looking holaster and a bunch of smaller mortoniceras ammonites. Check out the curvy fold in one of them. Poor dude went flaccid right when he hit the bottom of the ocean. Lol..I decided to flip a huge rock I’ve walked by many times (natural for me as a snake chaser) and I’m glad I did, I found a robust 2 inch wide x 8 inch diameter mortoniceras attached within the rock. It’s beyond my ability to easily free it, but I will get it done with some help. Nice calcite on the outside where I broke away some matrix. one of the morts is a mess (the one with the green algae on one side), it’s beautiful but I’ll have to make a decision about leaving it as is or cutting it to the point where it’s complete on both sides.

I only had 1.5 hours, but it was worth it. I ran out of daylight a month ago when I was at my local creek, so I went back and walked the portion I couldn’t see due to darkness last time. 4 nice mortoniceras ammonites, looking good on both sides (one is a bit worn due to weather exposure). Another one was broken down the middle, but I glued it and I’ll make it a rehab project. How about the perfect scallop too? I rarely find them complete and unblemished.

I am going to give this N Texas ammonite away to a kid this weekend on a fossil trip that I am leading in the mountains of central Arizona. This lower Cretaceous ammonite was probably collected from the Fort Worth or Duck Creek Formations. Could it be a Mortoniceras? Thanks, John

Greetings all, My wife and I were heading back to Altus AFB (where I am currently training), after a weekend away in Dallas. We decided to make a brief detour to Lake Texoma, and the famous "Ammonite Beach." Parking by the dam, we followed the southern coast west for a little over half a mile. We passed a few (what I believe were) fossilized shrimp borrows and a couple of oyster shells. After turning the corner around one of the points, it was quite clear that we had arrived! The location absolutely lived up to its reputation, and we quickly faced a paradox of choice, in terms of which ones to bring back with us. Unfortunately we were only able to spend an hour searching, as we didn't want to contend with the storm system that recently hit the central part of the country during our drive home. All-in-all, it was a very productive trip, considering how briefly we were there. We found a few fragments, and a couple of relatively complete specimens. For one of those, we were able to extract both the fossil and the negative, which is always fun to show to people. I'm hoping that the central portion of the ammonite is present on the far right specimen, but don't want to touch it until I build my fossil prep station (e.g. micro sand blaster, air scribe, etc) after I move up to WA, later this spring. We will definitely be going back once more, prior to departing Oklahoma, to search for that "statement piece" for our collection. That being said, I've also heard that various echinoids can be found in the vicinity as well. I didn't see any, but I honestly didn't spend too much time searching closely for them. If anyone has any recommended sites for echinoids at or near Lake Texoma for a subsequent trip, I would love to hear about it. Cheers! -Nick
