One week fossil collecting trip out west, my sixth time in the past six years. Flew into Denver. Rented a car and headed down to Castle Rock where I spent the night at a motel. Next day drove up to Florissant Fossil Quarry. It was Wednesday and they're normally closed during the week in September, but I made special arrangements for a few hours visit. Compared to my two previous visits there, didn't do as well. The other times, I was there for the whole day, this time was just for three hours, and they had had a considerable amount of rain recently and so the shale was more crumbly and more difficult to split. Here are some of my finds. Plants:

Herpetology is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts and the gymnophiona) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians and the tuataras). Long, long before my endeavors in amateur Paleontology, though I did not know what to call it at the time, my childhood passion was amateur Herpetology. Anywhere I went, that's what I was looking for. If you were to ask what I wanted to do, that would be it. There were empty lots near my house (which are now Petco and Target) that I called "The Mesa" that were chock full of lizards of all shapes...my parents tell stories of having to drag me away. As I grew older, other things began to consume my time and I figured I out grew that phase... ...nope, not the case! My BFF is quite fond of reptiles and amphibians and has reignited that flame. This year alone we encountered 12 genus of herp in the wild, managing to document 10 of those with photos. Trachemys... ...Terrapene... ...Cnemidophorus... ...Crotophytus... ...Uta... ...Holbrookia... ...Scaphiopus and Spea... ...Bufo... ...Sceloporus... ...and Pituophis... ...that's one heckuva list! There was a insanely fast Coachwhip (Coluber) and a large bullfrog (Lithobates) that we could not catch. As Autumn blows through we are saying goodbye, for now, to our slimy and scaly friends...we will miss you! See you in the Spring! I make this post in memory of our beloved Merlin (Pagona)... ...we will always love you! To my Chickaroo...thank you, from the bottom of my heart, for the realignment! And to my Forum Family, post 'em if you got 'em...or you've seen 'em...or if your just a fan! Got Herps?

So over the last few years I've collected different rocks, fossils, and anything else I find that i think is unique. Eventually, I go through them and have a closer look. I'm sure my eyes are making things up, but, hey, why go om wondering when I can just ask?? I have some rocks here some found in Indiana and some in Ohio and I'm wondering if they are reptile heads of some sort(I'm assuming that's a thing people actually find lol) If you tell me they are rocks, I will believe they are rocks and will appreciate the knowledge. Thank you in advance! You guys rock(yes, pun intended)! Oh, and these are between a half inch to a little over an inch.

We've had a couple nice hunts in the Aquia recently. Our first trip was really nice. The weather was beautiful and the tide was low. The only finds of note from this trip were two shark vertebrae and a small yet pristine transitional otodus. As always, we found over a 100 teeth in the gentle shallows. Our second trip was incredibly productive, albeit with fast moving water and a high tide on a beach ravaged by storms. We found what I think is a turtle washing out of a recent fall; I was unable to spot the rest of the turtle in the fall, however we were able to grab five pieces of material from the same spot,(within 6-7 feet of each other) and then find four more scattered along the beach. This trip was also very productive in terms of otodus, 3 in all from this same trip, although one was very badly damaged. Along with these larger beauties, innumerable teeth found their way into our hands and pockets. Is there any way that the turtle can be identified? Is it possible to refer to this turtle material as from the same turtle? ( We weren't finding any the first trip and then found a ton the second trip) @MarcoSr@sharkdoctor@WhodamanHD Thanks, FA The rikers mount contains finds from both trips. The largest fragment of turtle. Identifiable?

I spent the day hunting the badlands of the Hell Creek formation in northwest South Dakota. It was beautiful outside. The sun was shining, the breeze was blowing and the insects were mild. The group started the day working the amber microsite- a spot where a phenomenal amount of amber is produced from lignite rich exposures mixed in with a deposit of smaller fossils. I spent several hours picking up amber bits along with a variety of other fossils. Here are some photos from the first few hours of the day Views of some of the collecting area A shot of the gravel where many of the fossils lie. Some pics of the amber- a small fraction of what I picked up. Several Brachychampsa alligator teeth. Left: A small Edmontosaurus tooth Right: A small digit, potentially turtle or crocodile Left: Small vertebra- amphibian? squamate? Right: Crocodilian osteoderm Left: One of my best Brachychampsa teeth to date Right: Awesome crocodilian tooth I left the amber microsite around noon to go prospecting with some other people, here is a view from atop a butte we found some fossils on. I found this awesome turtle claw after finding some shell pieces eroding from near the top of the butte. Since I found it among many pieces of softshell turtle shell I would assume it's a trionychid. As we moved away from the butte, we explored a dried creek bed which created a small valley with some exposures on the side. We found a few fossils including a champsosaur vertebra another cool claw. It belongs to another species of turtle, although I'm not sure what variety. I returned to the microsite to wrap up the day and was not disappointed by my finds. I found this Paronychodon tooth below the main amber site . My last big find of the day was this cool section of crocodile jaw. I found a ton of great fossils today and I'm crossing my fingers that tomorrow will be just as productive!

Turtles from China...again
sneakyelf posted a topic in Is It Real? How to Recognize Fossil Fabrications
Manchurochelys liaoxiensis from Liaoning province. These turtles have shown up in the forum before, some with the conclusion they are real, some not. Here is an incredible display of turtles with fish! However, I am highly skeptical despite coming from a reputable source. They seem to have a halo of color all the way around them. On extreme angles there are some parts where the shell is not attached to the matrix. Even the fish are "on" the matrix, not in it. It is not resin, as I have exposed many parts to a soldering iron. The crack on that back seems to run under, not through, the turtles but is visible on the front where the turtles are not. It even runs under, not through, a limb. To me, a best case scenario is that these "real" fossils were placed onto a stone slab, but that seems like a lot of unnecessary work. If the turtles are casts that are put onto the matrix, is there an easy way to tell? Would x-ray be useful as the turtle and the matrix are likely different densities if the turtles were added on? And can anyone recognize the fish? If they are millions of years apart, that might answer the question. but where are the heads of the fish? Llastly, for a fascinating read on fakes, check this out: https://www.researchgate.net/publication/265208436_Fossil_fakes_and_their_recognition This is not the site of a seller, so it should not break the rules of this forum...if I am not mistaken. Thanks for your thoughts!

An opportunity for TFF members to help us create better programs
fossilsonwheels posted a topic in General Fossil Discussion
We had two really great Dinosaur programs this week. We have two more Dino programs and a shark program next week too so things are rolling along very nicely for us. I did notice this week that we are missing out on an opportunity to give a broader picture of the paleoecology of the dinosaur era. The kids yesterday wanted to see Pterosaur and marine reptile fossils. We had a chance to really explain the difference between those reptiles and dinosaurs because we have yet to acquire those fossils. I wanted to open this topic to TFF members because I respect the knowledge of fossils and the animals that left the fossils behind that our friends have. We need to round out our programs and I need to begin learning more about dinosaur age animals that were not dinosaurs. We do have croc teeth that will start going with us and I am putting together a display of dinosaur era shark teeth to keep in the dino program bin. Now that I have a better handle on how much material we can fit into an hour long program, I can tighten up the program and find a few minutes to cover non dinosaurs. This is where we need your help. I want to know what critters from the age of dinosaurs you think we should be touching on. What animals do I need to start looking into getting fossil representatives from and what critters do i need to study ? I thought it might be really fun to get the opinions of our friends and have the great minds here contribute to the material cover. This is open to all forum members so give us your thoughts and knowledge. Help us further our education goals by creating a more well rounded program !- 23 replies

Although not the same fan fare as with Dinosaurs my collecting days has yielded some very cool turtle specimens. Channel deposits deliver a host of species which include Fish, Crock, Reptiles and Turtle. You never know what the next flip of the knife will deliver and skulls are as good as you can get. Lots of broken ones but every once and a while a complete one surfaces. I am not that knowledgeable on identifying turtle specimens so bare with me if you see something misidentified, just let me know. I have a pet Dog but I call these skulls my PET FOSSILS. They are a lot easier to maintain no walking or feeding required. I don't have names for them but just enjoy them and are always a big hit with everyone. My first skull is in the Trionychid family softshell turtle. Very cool skull looks like it has arms for walking. Identified it as Axestemys byssina (8 1/2" - 22cm) Long Hell Creek Formation Perkins Co., South Dakota The next skull is in the Baenid Family Identified as Bubaena cephalica the atlas vertebra was found with the skull. (3 1/2" -8.9cm) Square Hell Creek Formation Powder River Co., Montana Same as above just slightly smaller specimen at 3" (7.6cm) long, same locality The next skull is also in the Baenid Family Identified as Palatobaena choen approximately 2 1/4" (5.7cm) square. Very odd shaped nasal opening Hell Creek Formation Powder River Co., Montana Same as above just slightly smaller specimen at 2" (2cm) square
