Partial Jurassic Neuroptera Insect with Beautiful Wing Preservation
Biotalker posted a topic in General Fossil Discussion
Here is my recent acquisition from Inner Mongolia of China in the Jiulongshan formation, more commonly and famously known as Daohugou, which dates to middle Jurassic around 165 mya. The part and counterpart partial insect fossil appears to be a neuropteran, perhaps related to the family of Grammolingiidae (a group of lacewings that include “Jurassic butterflies”, so named on account of their huge spotted wings). Only one of the wings and a small part of another were found in the fossil. The wing, however, is slightly more than two inches (5cm) long. The head and thorax but not the abdomen are- 8 replies

Interesting piece found in the junction bed Jurassic layers in Somerset. Bone like texture. Possibly ichthyosaur?? Any help much appreciated. Found amongst Jurassic ammonites layers.

Hi My wife and I have just returned from a relaxing week on the Yorkshire coast, walking and looking for ammonites. We didn’t find much but what we did find were pretty rare. First some scenic pics: The last is Whitby Abbey which features in Dracula. First ammonite, an Asteroceras multi block. Second, a androgynoceras multi block Third Paltechioceras (extremely rare and needs glueing back together and prepping)

Hello! I am wondering is this caudal vertebra is from a diplodocus. I have learned over the years that sellers just slap a ‘Diplodocus’ label on anything that looks remotely diplodocid like. It is 22 cm long and 19 cm high and collected from Dana quarry Wyoming. Thanks.

Ever Wonder Which Morrison Dinosaurs were most Abundant?
Troodon posted a topic in Questions & Answers
Ever wonder which Jurassic dinosaurs in the Morrison Formation were most abundant? Well at least those collected. Dr Susie Maidment posted this on twitter "Hey Morrison Formation fans! Ever wondered what the most abundant dinosaurs in the formation were, based on PBDB data? I did, and I plotted it" Looks like the winners were, no surprise Sauropod: Camarasaurus Theropod: Allosaurus Ornithischians: Stegosaurs- 15 replies

Best tools to prep Morrison formation material
Fossil Collect posted a topic in General Fossil Discussion
Hi, I’ve been wanting to prep some Morrison formation material for a while now however I’ve never prepped Morrison stuff. I have prepped many Hell creek and lance creek fossils. So what are the best tooth for preparing Morrison formation material specifically things like sauropod and theropod vertebrae’s? Thanks! -
Hi everyone. I recently liberated this rather nice ammonite from a block found in a ploughed field near Chippenham, Wiltshire, UK. I believe it to be a Quenstedtoceras from the Kellaways beds (Callovian age). I'd really appreciate it if a more learned member could confirm this. My track record for self ID's thus far has been atrocious!

It was found in a ravine in sedimentary rocks from the Upper Jurassic, in Spain. The rock surrounding the fossil is conglomerate, sandstone, siltstone, and clay. The fossil is approximately 2 centimeters long and has an irregular cylindrical shape. It is brown with some darker parts. One of the edges in its transversal section has shiny white spots as if it were crystal. The outer layer has a texture like veining along the cylinder. It may be a fossil of a marine creature that lived during that time, such as a mollusk shell, a shark tooth, or a fish backbone? Belemnites: T

Hello! I hesitate to post after my last terrible misidentification of fossilised wood, but your kind help made me study harder, learn more, look harder - thank you! So I’m back with another request - I think I might have actually found wood this time? These are all from the Kimmeridgian Helmsdale Boulder Beds or nearby Portgower Boulder Beds, Scotland, UK. Dark photos are wet, mostly they go quite pale when dried out. In this case, I know wood is a known find in these areas, and I’ve found a scant few photos from seasoned collectors / geologists of finds fr

Giant Dromaeosaurs and other Eumaniraptora from the Cretaceous period
Joseph Fossil posted a topic in Questions & Answers
The Eumaniraptora is a clade of non-avian theropod dinosaurs that first emerged during the late Jurassic period and diversified extensively during the subsequent Cretaceous period (143-66 Million years ago). This group is most famously known as the Raptor dinosaurs (the sister clade of the theropod dinosaurs that gave direct rise to the birds), consisting of mostly small to mid sized theropod dinosaurs. There are a few species though that exceed the typical small-medium size range for the raptor dinosaurs. Only a few giant raptor dinosaurs are currently known. But recent discoveries over the p- 2 replies

Hi all, Bought this tooth online a while back. It was sold to me as "Ichthyosaurus platyodon" (which I understand to mean Temnodontosaurus platyodon) from Lyme Regis. Likely found by the seller themselves, as I know they occasionally collect fossils there. However, for the following reasons, I'm not sure about this attribution: Overall, the tooth doesn't look like your typical ichthyosaur tooth to me: It has more of an oval rather than round cross-section It's labolingually flattened Messial and distal carinae run the full length of the cr

Belemnites have been my core interest for decades, starting as an 8 year old kid when I saw and bought the pointy end of a large Cylindroteuthis in a curio shop (I still have it ). This led eventually to being able to research some Lower Jurassic ones for my Ph.D at university. I pursued another career after that (musical instrument repair and restoration) but palaeontology has remained a fairly fanatical interest ever since. Most of my early collection (including nearly all the research stuff) has been lost for various reasons but I've been able to replace much of it and added many new

rare Coelacanth in unusual preservation. Seems to be Coccoderma, perhaps part of a meal. Fantastic skin preservation and good skull. Back part and tail got lost in the field, so I do not know how complete it was. Size is approx. 14 cm what you see. Was found in Eichstaett many years ago, comes from an old collection-

Roughly two years ago, while investigating the identity of a marine reptile tooth said to have come from Lyme Regis, I got hinted about a spectacular new marine crocodile, much older than any other member of the thalattosuchian clade. This new species has finally been described: Turnersuchus hingleyae! Set outside the traditional subgroupings of teleosauroidea and metriorhynchoidea, this newly described species has major implications for the evolutionary relationships between thalattosuchians and other crocodylomorphs.

Happy New Year! I'm looking for some suggestions on how to more effectively prep some Dactyloceras. These are in Whitby nodules. The matrix surrounding them is too small to split. I've done a few with a dremel using Zoicpaleotech points with some success. But the inner whorls are not coming out as I'd like. I would appreciate any help Thanks!
