  1. There is a very interesting paper about the tracks of footprints of birds, pterosaurs, dinosaurs found just below the K/Pg boundary in the Las Encinas Formation, State of Coahuila, Mexico. Although the PDF is in Spanish, a more or less usable translation can be obtained using document option of Goggle Translate. The open access paper is: Serrano-Brañas, C., Espinosa-Chávez, B., Flores-Ventura, J., Barrera-Guevara, D., Torres-Rodríguez, E., Cadena-González, D., and Vega, F.J., 2024. Huellas de aves, pterosaurios, dinosaurios y el límite K/Pg en Coahuila, México (Footprints of birds, pterosaurs, dinosaurs and the K/Pg limit in Coahuila, Mexico). Revista-Maya-Geociencias, Febrero 2024. pp. 96-105. LInks to PDFs of Febrero 2024 and other issues of Revista Maya Geociencia A related paper is: Serrano-Brañas, C.I., Espinosa-Chávez, B., Ventura, J.F., Barrera-Guevara, D., Torres-Rodríguez, E. and Vega, F.J., 2022.

  2. Probably among the most spectacular creatures of all. So please show us your Pterosaurs material and if you can add a image of the creature thank you. Pterosaurs and dinosaurs belong to a group called the Archosauria, which includes crocodilians, dinosaurs (including birds) and pterosaurs. Archosaurs share a number of characteristics including a hole in the skull in front of the eye and teeth set in sockets. They were the first animals after insects to evolve powered flight, and the largest creatures ever to fly. The animals varied widely in size, from Nemicolopterus cryptus, which is about the size of a finch, to Quetzalcoatlus northropi which had a wingspan of more than 33 feet. Scientists and artists once imagined many ways that pterosaurs might move on land, including upside down in trees like bats, was a popular art motif in 1960s or 1970s many of these paintings have aged badly scientifically but still incredibly beautiful. Pterosaurs lived from 220 million years ago to 66 million years ago, when they were wiped out with the non-avian dinosaurs. This is my treasured specimen, small and not perfect but very rare from this location . Coloborhynchus from Bexhill Wealden UK . Coloborhynchus was a giant pterosaur flying reptile and the largest toothed pterosaur. Size of tooth: 1 cm in length. I hope to add to this post in the future. To end with a bad joke as a thank you for reading “Why can’t you hear a pterodactyl go to the bathroom. The “p” is silent. all the best Bobby

    2021 Richmond Trips

    While 2021 was an extremely difficult year with coivd and the loss of my mother we were able to make it out to Richmond in NW Queensland for 2 fossil digs. The conditions out here can very harsh 40c plus days so we did a bit of night time digging under lanterns to avoid the heat. The material here is marine cretaceous sediments from the Toolebuc formation. Our goals this year was to finally find a large ichthyosaur bone (I have found 2x isolated teeth in the past) and find a NW Queensland ammonite. Below are some of best finds from the two digs. While the ichthyosaur bone eluded us for another year while going through our material we brought home we found what has been ID as a Pterosaur digit bone which we were very excited about as these are rare in Australia as is by far my most exciting find to date the fossil is approx 8cm long. Another rare fossil from the site is Johnlongia shark tooth we have found average condition teeth in the past but this year we found a very well preserved one. While turtle fossils are very common on this site we did find our first almost complete one however it was very fragile so decided the best option was to leave it in the location we found it . (Sorry these pictures were taken at night so are not very good) Another very common fossil is fish remains however we found our best fish jaw to date this took quite a few hours to prep. Lastly I was determined to find at least one Ammonite these are not found in our usual site so after been given some guidance and contacting land owners we were given permission to hunt on a station which was well known for ammonites and it didn't disappoint we made some nice finds. The best part of the fossil hunting this year was spending quality time with my son who loves doing it too, thanks for reading my run down of this year collecting I hope everyone has a great 2022. Cheers

    Please ID these!

    All of these were found on gravel bars on Elm Creek in north-eastern Kansas, as we kayak on it a lot.

  8. Aloha, here is the best of my collection. Since I moved together with my girlfriend, only the small and nice samples are on display, one showcase out of three. Looking forward to the day when we will have some more space. So it is a crowded mix of fossils, minerals, recent beachfinds and mosty selfmade or altered skeleton models. Sadly, only a small percentage of my fossils is selffound, although nearly all of the beach stuff is. There is the "poultry showcase", dedicated to Birds and pterosaurs (Parrot skull is a replica of course, as is the Pterosaur plate regrettably) The big showcase is a composite image because I could not get all into one foto. The whales you may know from the Palaeorecreation thread. Best Regards, J
  9. as a connoisseur of Pterosaurs, I wanted to ask the Community here to show me it's pterosaur fossils from the Kem Kem Formation. After seeing a rare Tapejarid Premaxilla recently get sold on a Fossil Dealing site (labeled incorrectly as Alanqa), I wondered what treasures could be present in Private Collections in this Community. Teeth are just as welcome as Bones are.
  10. I could have sworn I posted this already so if it is a duplicate, please delete it. https://m.phys.org/news/2019-08-filter-feeding-pterosaurs-flamingos-late-jurassic.html They looked at coprolite associated with Pterosaurs Trackways and it looked like they were filter feeders.
  11. 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 !
