    Herpetology

    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?
  2. The Permian-Triassic Extinction event of 252 Million Years (caused by massive volcanic eruptions in what is now Siberia) was one of the biggest mass extinctions in Earth's history (killing 75% of all land genera and 95% of all marine genera). The event marked the end of the Paleozoic and the beginning of the Mesozoic. Famous survivors of the extinction event include the Dicynodont Lystrosaurus, the Therocephalians Moschorhinus, Tetracynodon, Promoschorhynchus, the Archosaur Proterosuchus, and the Cynodont Thrinaxodon. One group of terrestrial survivors of the extinction event sometimes overlooked are the Amphibians, the original tetrapods. One resilient group not only survived the extinction event but experienced a rapid period of diversification during the Triassic. These were the truly iconic and mostly salamander like Temnospondyls (Temnospondyli). This group lasted from the Carboniferous until the Early Cretaceous period (330-120 Million Years ago). It’s also likely that they are the direct ancestors of today’s Lissamphibia (the most common group of Amphibians alive today). Here’s a list of all currently known amphibian genera and families that survived the Permian-Triassic Extinction Event. If I forget any examples, please let me know and I'll add the examples to the list promptly.

  3. HynerpetonHunter

    Red Hill Fossil Hunting

    On August 15 I went to Red Hill near North Bend, PA, with my parents, grandparents, and aunt along with my friend. The weather was not much better than now. It was searing hot. Our first stop was the North Bend Municipal Building, which housed the Red Hill Fossil Display. We met the discoverer of one of the earliest amphibians ever, Densignathus, named Douglas Rowe. He led us back to Red Hill, and we started to fossil hunt. I was determined to carry on the hunt for a good transitional fossil, like Hynerpeton. I immediately found a nice-sized Hyneria scale. After hunting for a good while, I had found lots of Hyneria material, as well as Turrisaspis, Ageleodus, Gyracanthus, Limnomis, and Megalichthys. But I knew that I could possibly never find a Hynerpeton in my entire life. But I kept going. Finally, ten minutes before we left, I found something interesting. I was right below the place where Daeschler discovered Hynerpeton back in ‘93, and was feeling the effects of heat exhaustion. I was ready to give up when I saw a rectangular, centimeter-long chunk of bone. I was intrigued, but I had no time for hand ID. I needed water ASAP. But the next day, I was observing a document of the fin model of Eusthenopteron. I noticed something small next to the fin support. It was rectangular, almost identical to my bone. It was a scute. To be sure that I had a scute of an amphibian like the one on the Eusthenopteron diagram, I looked to Ichthyostega. Sure enough, Ichthyostega’s scute was almost a carbon copy of mine. I had a Hynerpeton or Densignathus scute. Images of my fossils will be coming soon!
  4. Can anyone confirm this temnospondyl amphibian is Sclerocephalus häuseri? Thanks in advance. Unprepared about 70 to 80% complete fossil from the Permian of Germany.

  5. Hello everyone, I want to tell you my first experience with Microfossil. (I can't stop anymore, it's a drug). Anyway, last months I worked in the paleontology museum of my university. My role was pretty much to be a factotum but in particular I had to rediscover all the fossils that are in the deposits and in the basement. I can't describe you the tons and tons of unknown material there is. We already found many interesting and never described pieces. Anyway, back to our story, in the deposits there where dozens of bags full of fossiliferous sediments from Cava dell'erba in souther Italy a lower pleistocene/pliocene site known better for the macrofossils (Pirro Nord fauna). The bags need all to be sifted cleaned and studied, looking also for human remains. Three of these bags were unfortunately broken and all the sediment was mixed making it completely useless for any study (the sediment come from carsic fissures so the level and the position is very important). So the museum director told me that sediment was going to be thrown away, or if I wanted I could bring it at home. I clearly took it with me, I washed sifted and collected and here are my preliminary results. The photo represents all the teeth and mandible I found there are insectivors rodents amphibian, there is also a canine (from what it can come from? It's the second from right in the second row) I still have a bag to study and tons of bones to identify, I'm gonna ask you some help very soon
  6. I finally finished going through my Oklahoma Permian Matrix from PaleoTex LLC! SO MUCH STUFF! I went through it the first time just with eyeballs (with the help of reading glasses). Then I realized I should use my microscope camera (which runs through my computer which is AWESOME) and see if I missed anything. OH MY GREAT GOOGLY MOOGLY I missed a lot! So here are some of the really "minis" from the matrix! Most are so small that it just couldn't even get a pic with my scale, some are less than 1 mm - a speck of dust! . I need to get a millimeter scale, though, for sure. So here are some more finds from the Oklahoma Permian: Mycterosaurus tooth : 4 mm Chevron Bone (part of the tail of an amphibian, I believe? 4 mm A Doleserpeton toe bone! So very tiny. You can see how small it is compared to the 4 mm chevron! I think this is an intervertebral thing? 2 mm Unknown tiny tiny. Can't seem to find out what this is, but I thought it was really really cool looking . It was literally the size o a speck of dust.... which sadly meant I lost it after I photographed it....it just disappeared. a lovely bone. 3 mm Jaw plate...i loved the blueish enamel: 3 mm Same with this "blue tooth" - probably Cacops, I think? 3 mm Another Cacops tooth: 4 mm An unknown jaw fragment: 3mm Captorhinus tooth? 2 mm Doleserpeton jaw plates biggest 2 mm and lastly a Diadectid tooth There are so many more little bones and teeth and jaw plates and vertebras and skull fragments!! Needless to say, it's been great fun looking through all this tiny matrix. i am totally hooked on it!
  7. Hello! Long story short, my fossil collection perished in a house fire when I was a kid. I realized a few years ago that I was a Real Adult™ who didn't have to ask for parental permission to buy stuff and could rebuild what I'd lost, so after acquiring my first piece of amber – a big fat spider in Dominican Amber – I was hooked. Researching and buying fossils has been so fun and informative; I've been burned a few times with fakes, I've celebrated rarities, and I love having a little museum in my apartment. This past weekend I did the Museum of Natural History Sleepover in NYC and had a blast talking to an expert in the dinosaur wing, something I couldn't have done without this forum and a total crush on fossil trading, learning along the way. My current stash is focused mainly on claws, teeth, bones, plates, and anything encased in amber. Here's my main collection, with detailed photos and labeled descriptions to follow. Also, if anyone has further identification, feel free to chime in. You're the experts. Detailed pics and labels to come.

    Hungry boy

    Here is a hungry boy from the Permian that I drew.Not yet sure if I like the way I drew the sand clouds, and I think that using pen for the final product was definitely a mistake, but otherwise it is okay.
