Some Say Lightning Doesn't Strike the Same Place Twice...
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Return to the Badlands of North Texas At long last, rain graced the lands of North Texas this past week. For many of us, that meant it was time to finally crawl out of bed and beat the crowd to that one particular site desperately needing a refresh. In my case, I set on my way to explore a newer spot in the Grayson Marl while the ground was still nice and muddy. I'd been to this place once before, but it had already been thoroughly picked over. It's a popular site, but even then, it managed to pull through and produce some fine specimens for me to take home. With that in mind, I su- 9 replies

Crabs, Ammonites, Gastropods, and More! A Texas Invertebrate Sampler
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Over the month of December, I've gotten the opportunity to check out several sites across the state of Texas. In my fossil interests, I have to admit that I am certainly a bit vertebrate-centric, but that does not mean I will pass up the chance to marvel at a beautiful invertebrate specimen when given the chance. For better or worse, these past four mini hunts have not really delivered on the vertebrate end, but have made up the difference in terms of inverts. I've decided to combine these smaller hunts into one report. For those with invertebrate addictions, I hope this sampler of Texas fossi -
On Wednesday, November 30th, I took yet another trip to my micromorph spot in the Graysonites wacoense Zone of the Grayson Marl Formation, Washita Group of north Texas (Lower Cenomanian, ~97mya), laterally equivalent to the Waco Pit in the Del Rio Fm. further south. This time I focused mainly on looking for shark teeth which was a massive success, and I ended up finding a few new species to add to my faunal list for this location as well. The first find of the day was this nice small lateral Cretalamna catoxodon (Otodontidae) shark tooth, the most common shark species at this site:- 22 replies

A Day of Micromorph Ammonites, Shark Teeth, and Urchins in the Grayson Marl Formation of North Texas
Aidan Campos posted a topic in Fossil Hunting Trips
Here are just some of my finds from a day spent in the Graysonites wacoense Zone, Grayson Marl Formation, Washita Group of north Texas (Lower Cenomanian, ~97mya) last Sunday, November 13th. This is my second visit to the site, which is equivalent to and faunally almost identical to the Del Rio micromorph exposures of further south, today only present at a couple sites in the DFW area. Starting off with the first find which happened to be my first complete (sans spines and Aristotle’s lantern of course), and largest Goniophorus scotti (Goniophoridae) urchin:- 10 replies

Found this hunting new place at Woodbine/Grayson contact, there it was nestled in the lower layer of grey-blue marl sporting the same color. Last time I checked there weren't crinoids in Grayson, so how did it get there? Have only a handful of fossils this color from there including this bivalve I can't ID, or is it a brachiopod?

I've never seen these little things before anywhere, the only place they are on this is on the ammonite itself. Some kind of trace fossil of a parasite? Embryo stage of something? From Grayson formation.

Impromptu Construction Site Hunt. Grayson Marl and Pawpaw Formation
EPIKLULSXDDDDD posted a topic in Fossil ID
Following a refreshing swim at the lake with a few friends over the weekend, I decided to take a spur-of-the-moment stop at a construction site I happened to be driving by. The sun was setting, cooling the area and finally making it hospitable despite the recent heat wave. I was not familiar with the exact geology of where I was, but with only an hour and a half of daylight left I decided to not waste too much time and immediately began scouring the dirt. I quickly noticed that the ground was composed of two distinct formations. The higher layer was a grey limestone while the layer- 7 replies

This was found at same location as Rockwood's tooth, Grayson marl Washita group. I'm still getting familiar with things here and this is first tooth I've found and hopefully it's Ptychodus?

Just washed off couple pounds of dried mud on my shoes from my outing yesterday to Grayson spot. Was delighted to find another fossil! I have not been able to ID it, first I thought deer heart clam but I see the hinge, is this a Brachiopod?

Teeth? Or am toothbrushing rocks? Sand continues to shed and seem to be shaping. Hunt County. Bazaar Sedimentary rock. Only one I've seen like it. Looks like sea coral . Hunt County. I would have completely discounted this because of how white it is except for how it was found and how it looks.

Does anybody know where to access these Kennedy papers? Everywhere that I can find them they need to be requested. Thank you in advance.
