Interesting article in the NYT (New York Times) today on a fossil lizard called Megachirella. You may need subscription to view. However, they usually allow a certain number of free viewings per month. You might include this in yours. Cheers. Megachirella article

Any ichnofossil specialist in there? Ichnofossil from Brazil Jurassic ID
Aerson posted a topic in Fossil ID
Hello everyone. I'm a geologist/stratigraphist and I've been studying Missão Velha Formation (Araripe Basin, Brazil Jurassic-Cretaceous) for a couple of years. We found some structures that seem to be trace fossils, but as geologists, we assume ourselves to be slightly ignorant in ecologic behavior of species. The MV Formation are corsed sandstones, well stratified, with few purple siltic-sandstone levels with ped structures. These trace fossils I'll be presenting next resemble the top of one of these siltic-sandstone levels. They are tridimensional and cilindric, with an spheric edge on the bottom and the top is not well seen. It have sort of a stratification, like it was many piled up rings. -
Looking for literature on the cycads and bennettitaleans of Lune River, Tasmania
paleoflor posted a topic in Fossil Literature
L.S., As the title says, I am looking for literature on the cycads and bennettitaleans of Lune River, Tasmania. This Jurassic site is world-famous for its fern fossils, with numerous papers written on them, but it turns out to be quite difficult to find specific information on the other groups of plants that grew there. Hope you can help. Kind regards, Tim -
I found this fossil in Gerstetten, Germany. It is late Jurassic, 145 million years old and was found in limestone. Does anybody know what it is?

Hello everyone! As my family was making its way through northern UT this summer on my way to Dinosaur National Monument I realized that there would be some extra time in the afternoon between when we would arrive in Vernal and when we would check into the hotel, so I decided to do the only logical thing and find a place to go fossil hunting for a few hours in the surrounding area. One of the sites I found only talked about finding belemnites, ammonoids and oyster shells on BLM land off of the highway going into vernal. It was supposed to be middle Jurassic Curtis formation (according to the geologic road signs, an interesting feature of this area's highways). I followed the directions given on the website and we reached the area that we believed to be the one mentioned (The Rockhounder: Belmemnite Fossils Near Vernal Utah) we met a young couple and their toddler out hunting for fossils (always nice to see). What we found somewhat disappointed me (however any afternoon spent fossil hunting is automatically better than any not doing so), only brachiopods and not one cephalopod fossil to be found. The main point of posting this in ID is to figure out if these brachiopods are jurassic species or older, as no belemnites were found they couldn't be used as indicators to the true age.

Dimensions: 185mm long Location: Atlas mountains Jurassic outcrops, Morocco I'm having trouble identifying this partial fossil bone. It's only smallish piece with some significant old broken sections but it still has a pretty distinctive blade-like shape and the internal structure visible at the end breaks is interesting. My amateur impression is that it's too straight for a rib, it's asymmetric so not a chevron, so I was thinking maybe a fibula, or perhaps an ischium or scapula. Any input welcome.

From the album Dinosaurs & flying reptiles
Eubrontes: Dilophosaurus ? Raised relief (footprint coated to stand out). 200 mya Triassic Erving, Massachusetts . Connecticut River valley. Clay sandstone **Sadly, something smudged the tip of the middle toe while still wet, and ruined the beautiful claw mark. Heel to middle claw tip = 10", & from tip of right claw to top of left claw = 8". The 2 main types you commonly see are Eubrontes and Grallator, but Eubrontes is different, as it is apparently understood to be pretty much dilophosaurus footprints. (Citation???) I know there are probably sometimes others' footprints that will fall under the name, but it seems to be to the point of Eubrontes almost being synonymous with dilophosaurus. (Citation???) I KNOW I'm going to take flak for labeling this as just "dilophosaur", and I understand why, but all in all, in this case I feel completely comfortable and safe using the name without a qualifier. I'm very sorry to all who are bothered and annoyed by it -

Hello, TFF I was recently in Holzmaden, Germany when I found a piece of an octopus. I also recently read a book about octopus intelligence. This made me wonder if some prehistoric creatures might have been intelligent. I am especially interested in tool use, which has been observed in some modern animals. ( Octopuses, Cetaceans, Birds.) Has anyone found some possibly intelligent animals(fossilized?)

This is an Afrovenator tooth from Marraba, Niger (Tiouraren Formation). The fossil is in rough shape, but rare. I’m still working developing an eye for noting the differences, but still difficult for me..Having trouble determining if it is indeed Afrovenator, Carcharodontosaurus sp. , or undescribed theropod. I tried comparing different teeth, but still have issues. Any opinion on this appreciated.

Greetings. I have a lot of photos I’d like to share and get some feedback on, assuming there is not a unanimous agreement that the specimens you see in this photo are purely Geological in origin... I found them, and many more, within the geographical boundaries of a Jurassic age rock formation in Northern California that is listed primarily as meta volcanic rocks. Considering that information, please tell me if you thinking I’m barking up an imaginary tree here... If you are uncertain, let me know, and I will post more pictures... Thanks for your time! -Quinn

Araucaria Leaves from Russia?
Zapsalis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello Fossil Forum, I found a supposed Araucaria fossil leaf from the Russian Federation for a very low price on our favorite site, eBay. The dealer claims that the fossil is an unknown Araucaria species from the Upper Jurassic of Lena River Basin, Markha River, Siberia, Russia. Is this fossil legit and should I buy it?- 2 replies
