We often talk about how best to store fossil bones, here is what Matthew Brown does in collections at the University of Texas at Austin, posted on Twitter. Nice technique and can be applied to any bone or group of bones. Storage of a Dilophosaurus articulated leg that was shown in Nat Geo article. He made a cavity mount for a storage cabinet Brown "I cut a 2” plank of ethafoam to fit the drawer. You can do this in a small box for one bone, or fill a shelf. I traced the bones with a pen and cut them out with a hacksaw blade, test fit the bones, and pushed the cut-out piece to depth and cut the excess flush from the back." Brown "Once the cavities are cut, the next step is to line them with Tyvek. I cut the Tyvek larger than I need and crinkle it up to soften it. Using a scalpel, I cut a slit all around the bones about 1 cm away from the edge of the cavity. Always size the Tyvek bigger than you need it." Brown "I use a sculpting tool to tuck the excess Tyvek into the slit (about 2-3cm deep), moving along the perimeter until the Tyvek is neatly tucked. Using scissors, excess material can be trimmed away to make the tuck neater." Brown "Work your way around each bone until you’re done! I like the way this method maintains association of the elements without having them in physical contact, supports bones that arch, and protects the specimens against reckless drawer-yankers who might be visiting your collection"

Real Dilophosaurus Tooth?
Huntonia posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this Dilophosaurus tooth for sale online and am suspicous of its authenticity. The problem is I don't know a lot (or anything) about dinosaur teeth and how one would go about spotting a cast. Any advice would be appreciated, thanks.- 7 replies

Hey guys, wasn’t sure where to put this but anyway here we go. I was wondering if any of you have or have pictures of some fossils of some of my or your favorite dinosaurs?(I know gryposuchus isn’t a Dino too ) They are the species tagged. I know they are very rare and hard to obtain but just thought I’d see. Thanks, and I look forward to seeing your collections!

Hands are very important to everyone including Dinosaurs .. here are some photos of your not so ordinary ones ........both herbivore and theropod. Some pretty cool configurations.. Paper on the evolution of Theropod dinosaur Hands https://onlinelibrary.wiley.com/doi/full/10.1111/joa.12719 The evolution of the manus of early theropod dinosaurs is characterized by high inter‐ and intraspecific variation Daniel E. Barta, Sterling J. Nesbitt, Mark A. Norell First published: 08 November 2017 https://doi.org/10.1111/joa.12719 Have to thank Joao Vasco Leite for a bunch of these photos and info.from Twitter From the Triassic dawn of Dinosaurs here is the left hand of Herrerasaurus from Argentina Also from the late Triassic a sauropodomorph Plateosaurus, a beautiful specimen From the Early Jurassic of Argentina the ariticulated hands of the sauropodomorph Adeopapposaurus , wow The Jurassic brought us Dilophosaurus and sorry Jurassic Park fans there is no conclusive scientific evidence that it could spit poison Staying in the Jurassic here is Allosaurus and the different growth stages of its hand claws Also from the Morisson the tiny hand of the herbivore Camptosaurus The Jurassic also brought us the exquisite left forelimb of the stegosaur Gigantspinosaurus, from the Zigong Dinosaur Museum Stegosaurus hand material is quite rare, especially fairly complete ones. Morisson Formation One of the classics, first described by O.C. Marsh back in 1884. The left hand of Ceratosaurus. The bone to the right is metacarpal I, the first bone of the "thumb" . Have to wonder what it was used for. The Late Jurassic theropod Tanycolagreus ..cast From the early Cretaceous the hand of the recently described alvarezsaurid, Bannykus from China Also from the Early Cretaceous of Utah the left hand of Cedrorestes an iguanodontian Everyones favorite the hands of Deinonychus
