JamieLynn Posted May 11, 2023 Share Posted May 11, 2023 Well, you have probably already seen a few posts about the Dallas Paleontological Society's field trip to Ash Grove Quarry in Midlothian Texas. And Here's ANOTHER ONE! As it turns out, quite a few of us went on the same field trip but DIDN'T REALIZE WE WERE ALL ON THE SAME FIELD TRIP. That's what happens when you are mostly online friends and havn't actually met in real life! That and there were 50 people on the field trip....but it's a big quarry! Sorry I missed connecting in real life with @EPIKLULSXDDDDD, @PaleoPastels and @ClearLake! This actually was my first field trip with DPS and first time to this quarry so I wasn't very sure how things would play out, but we had a beautiful mostly cloudy day with a very nice breeze. As many of you know...quarrys in Texas can be brutal. We've been having surprisingly rainy and coolish weather, so it truly was a great day for hunting. Nice big rain the night before but not super muddy. Driving into the Quarry: I told you, there were a BUNCH of us The guy leading the trip, Francisco was really nice, made sure we were all geared up in our very very fashionable vests. He led us down to the bottom of the quarry where they had just placed a big pile of the strata we were looking for, so we didn't have to wander very far to find the right geology. Roger Farish, the DPS trip leader showed us what we were looking for...greyish rocks with lots of phosphate nodules. Most of the fossils are phosphatized, so the black was somewhat easy to see against the dryer grey, but in areas where it was still wet....that black was a bit tricky to see against the background. My first nice find was a good size Scapanorhynchus (goblin shark) about 3/4 inch long. And then a bit later in some of the pools of water, a lovely vertebra, also 3/4 inchish And there were some very nice big spiders. Don't worry. They were friendly. But.....what made my day, my month, my year was the next find. I found a Plesiosaur tooth. Yep. It was just sitting all nice and pretty on top of a small bank of mud and rocks off to the side, just sitting there waiting for me. It's kinda scrappy, but I don't care. I love it. I literally was shaking when I took it over to Roger F for confirmation it was indeed what I thought it was. So thank you Mother Nature! Here's some cleaned up and better pictures. It is one inch long So after that, I was just happy to wander around, maybe find something else...kind of wanting a Ptychodus tooth but content if I didn't find one and lo and behold....I see a tiny edge sticking out of a big chunk of rock and thought that sure looks like a ptychodus. I chipped it out and yep, a nice, if slightly broken, Ptychodus atcoenses. Not quite as nice as the one @ClearLake found, but I'm pleased with it. So a 3 1/2 hour drive up, a few hours of hunting and then drive back home again turned out to be totally worth it and an epic day for me. I found a plesiosaur tooth!!!! 1 22 www.fossil-quest.com Link to comment Share on other sites More sharing options...

ClearLake Posted May 11, 2023 Share Posted May 11, 2023 Very nice! I heard a rumbling during the trip that a Plesiosaur had been found, now I know it for sure. Way to go! Link to comment Share on other sites More sharing options...

Mikrogeophagus Posted May 11, 2023 Share Posted May 11, 2023 Awesome finds! You had a great hunt! Not trying to argue with the ID on the plesiosaur, but if I had found it I totally would've thought it was Xiphactinus. How exactly do people tell the two apart? 1 Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted May 11, 2023 Share Posted May 11, 2023 Congratulations! Next challenge -- Mazon Creek Tullymonster. That should keep you hunting for a few years/decades.

JamieLynn Posted May 12, 2023 Author Share Posted May 12, 2023 @EPIKLULSXDDDDD from my understanding, xiphactinus teeth have a "football" shaped cross section...having slightly tapered edge carina while plesiosaur are rounded with out that edge. But I am not an expert on this. Perhaps it is..... 1 www.fossil-quest.com Link to comment Share on other sites More sharing options...

Xiphactinus vetus teeth are football shaped in cross section (have carinae). Xiphactinus audax teeth are round in cross section. X. vetus is an eastern species while X. audax occur more to the west, including Texas. 2 Link to comment Share on other sites More sharing options...
JamieLynn Posted May 12, 2023 Author Share Posted May 12, 2023 So @Al Dente as much as I don't want to hear that what I think is plesiosaur might be actually be xiphactinus..... what is your opinion on this tooth then.

I don't have any experience with Texas plesiosaur teeth. I'm used to seeing some type of striations on plesiosaur teeth. Xiphactinus teeth are usually smooth and glossy. Maybe @pachy-pleuro-whatnot-odon can take a look and give his opinion. 1 Link to comment Share on other sites More sharing options...

Agreed that most Plesiosaurs have striations but not all. Here is a two-inch Plesiosaur I found in New Jersey which is actually pretty smooth (but does still show striations). That said, my confidence in my 'Plesiosaur' ID on the specimen in question has definitely taken a hit... I think I'm starting to agree with Xiphactinus.

frankh8147 Posted May 12, 2023 Share Posted May 12, 2023 And by the way, even if it's Xiphactinus, it's still a great find! Xiphactinus was one of the fiercest fish of all time! Link to comment Share on other sites More sharing options...
