  2. Aust cliffs

    Ok so some weeks ago I visited a friend in Bristol one of the days he was in work I ventured up north via public transport (which is always good fun especially when the buses run only every hour and stop at 6) so was limited on time a found a few rocks containing some surface but fragile fish scales, having never been there before I really should have thought on to bring some field tools but was a more spare of the moment type of thing, anyway so back home with the blocks and have just started processing them (and by them I mean 1 so far very nervously) by using a bolster and chisel and splitting along the sediment layers, first I was wondering if anyone has any tips on extracting fossils from this type of matrix yes it is limestone however I remember reading somewhere that using an acid such as vinegar can also damage the specimens. However what I have been ding is using a manual tool to very little effect and the dremel, the problem with this is the manual tool just isn't really helping with matrix removal and the dremel isn't chipping the matrix as effectively as I would hope and instead more crushes than chips (yes this is a dremel engraving tool however this vibrates rather than using a pneumatic action) the other thing I have been doing is using a syringe and very weak solution of b-72 protecting any specimens and using small amounts of vinegar on the surrounding matrix however again the amount that seems to be removed by the vinegar is minimal its probably soaking in to the matrix to be honest but I don't want to fully emerge the blocks and damage precious fossils, I understand this has almost become and essay of writing and was wondering if I should post in the preparations forum however I do have a few pieces I was looking for some id help with again first real exposure to fossils that are non dinosaur in origin, and first time ever dealing with this type of matrix. Any help is always appreciated Matt
  3. Dinosaur Footprint Cast?

    Hello, I found this last year during a fossil hunting trip in the Bendricks, South-Wales. I know their are several track ways and some 200+ footprints embedded within the rock around the local areas, however I have not seen a footprint cast from this locality either (that I know of). I have tried finding a contact for the geology department at the national museum based in Cardiff, though it has been unsucessful. Any light you can shed on this would be much appreciated! It may be just a conveniently shaped rock, however it is always worth asking. Apologies for the picture, I've had to rely on someone else for the picture - it is slightly larger than than palm size. Local rocks are Triassic - approx 220 million years
  4. Partial Anarosaurus skeleton

    From the album Dinosaurs and Reptiles

    Partial skeleton of a Middle Triassic marine reptile Anarosaurus (relative of Keichousaurus) from Muschelkalk, Germany. B, C, F, G, H - close-ups of various limb bones and vertebrae D - 2 Anarosaurus teeth E - fish scale I - Nothosaurus mirabilis (?) tooth The last two finds make me think that it is actually a Nothosaurus coprolite with digested Anarosaurus remains and various fish scales.

Journal of Paleontology, 88(3), 2014, p. 457–474 Quote: "Although the lobsters were interpreted as having relatively durable cuticle, the shrimp discussed herein are characterized by having very thin cuticle that is readily deformed and oriented in a variety of positions. As a result, the description and interpretation of the morphology of the shrimp is, of necessity, a composite of several specimens; however, fine detail of many parts of the skeletal anatomy is exquisite." Characteristic is the extremely long rostrum, constituting 40 percent of the carapace length.

  22. Utah's Oldest Dinosaur Fossil

    Found this in the Forums Facebook pages its a paper that describes a sacrum from the Chinle formation of Utah. The Dinosaur Triassic record in Utah is pretty slim and this discovery helps increase their knowledge base. We've recently had posts on Triassic teeth and although this paper does not help us in that area it provides more information on late Triassic dinosaurs of the American west. https://www.utahgeology.org/openjournal/index.php/GIW/article/view/22
