From the album: Triassic vertebrate fossils
A 5 cm long Nothosaur vertebra from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). This one is kinda fragile so the prep work was hard. I often give up and tried it another time again. Here is an older state: And another picture of the current state:-

A 0.8 cm long Acrodus tooth with a nice structure ! Those are very common in some layers in the "Bonebed" in a quarry in southern Germany (Baden-Württemberg) but bigger ones are quite rare. Another picture:- 3 comments

Another fish of interest. Being sold as a Madagascan Triassic Fish - Australosomus merlei 7cm (and a small piece of fossilised wood.) Is this rare / unusual? And real?

Near the Dutch town of Winterswijk is an Eldorado for fossil lovers. A student has now analyzed pieces from museums and (primarily) private collections for his master's thesis. He found an amazing amount of almost completely preserved skeletons, between 242 and 247 million years old. The good condition is presumably due to particularly favorable development conditions. LINK

I happened to be in Gettysburg for the weekend, and I remembered an article I had read a while back. It said something about Dinosaur prints at the Gettysburg battlegrounds. So I took a trip to the location and took a look around, here’s the prints I could see with all the rain: Clearest two, it’s a foot and hand from Atreipus milfordensis.

Tried my hand at two different styles of drawing an icthyosaur. Don't exactly remember the species I was going for but I remember that it and the fish are both from the Jurassic. this one is a bit more realistic. and this is a cartoony representation.

Hi, First time post of this site so hopefully I’ve made it correctly, seems to be heaps of knowledgeable/passionate people here. Just wondering if anyone can indentify this for me? It looks like Fossiled pieces of bark. It’s approximately 60cms long, 25cms wide and 3cms thick. In three joining pieces. I found it near a quarry in Ipswich Queensland Australia that is mostly shale and contains Triassic marker plants such as Dicroidium. Any help would be appreciated.

The Prosanto Fm. is a (Furrer et al. 1985) " Small lagoonal basin [pool] in the intertidal platform of the Vallatscha Fm. with anoxic bottom waters. Agitated surface waters deposit tempestite layers as well as mud, which forms very regular drapes." Taxonomy from Bürgin 2004. Diagnosis (Bürgin 2004, p, 242): "A fusiform species of the genus tEosemionotus with a broad gill-cover, being one and a half times deeper than wide. Supratemporal commissure not continuous. Fringing fulcra on dorsal and anal fin minute. Twenty-seven or 28 vertical scale rows and 12-14 single scales in the row in front of dorsal fin. Flank scales moderately deepened and with a smooth posterior margin." Line drawing from Bürgin 2004, p. 246: Identified by oilshale using Bürgin 2004. References: T. Buergin et al.

Hi guys, last week I started studying so I don't have much time at the moment and because of that I can't be very active here. Nevertheless I could go hunting last weekend (related to my eighteenth birthday (so why I am still a youth member?? )). I was in a quarry near Stuttgart where you can find fossils from the Triassic. Looking for bones and teeth in the "Bonebed" there is quite strenuous but it makes always fun! Especially if you find something good And my best find was this lungfish tooth (Ceratodus): Never found something like that before so I am quite happy with it! It's about 2.5 cm long and I prepped it with my air pen and with my new sandblasting machine! The prep work took about 1 hour. I can't really estimate how rare such a find is but maybe @Pemphix can say more! Thanks for viewing

Need tips for recognizing a fake keichousaurus at a fossil fair
ziggycardon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, next month I am going to Paleotime, a fossil fair in Belgium and I am hoping to find a Keichousaurus fossil. Now I know their are lots of fakes out there (although after doing some reading on this forum most of them I came to the understanding most of them aren’t entirely faked, just enhanced, painted and composites) And I am going to be honest, I don’t really care that much if the Keichou is a little bit enhanced of painted. But I hope to find a specimen that is at least 75 % or more authentic. So I was hoping if you guys could give me some tips as to what I should look for when I examine a specimen I hope to buy, cause since I will buy it at the fair, I won’t be able to post picture here during the process. I know that these are some of the thing I already have to look for to enhance the chance of getting an authentic one · Missing bones · Broken bones · Strange or akward poses · Imperfections (fake always try to be as beautiful and perfect as possible) · Calcite cracks running through the skeleton · Looking for detailing in the skull like teeth and obvious skull fragments · Looking for paint with a magnifying glass · Taking a picture and doing a negative to see paint mischief · Looking for 3D relief on the specimen These are the things I know of the look for, but does anyone else have some tips for me on how to recognize it’s a genuine of faked piece. I will also be taking my LED Mini microscope 60x for on the phone with me for closer examination. Thanks in advance!- 12 replies

Hi! I have some question marks about some of my fossils that I bought early as a child. I have a tooth that was labelled as coelophysis, I know its not a coelophysis, everything about it is wrong for being that, I cant remember where it was found , but if someone has an idea what it possibly/maybe can be its good enough for me. The other fossil is a dinosaur Bone fragment which according to what i can remember is from hell creek formation and was labelled as triceratops. Im mostly curious to know why it looks like it does because it doesnt look like a normal fragment to me, it also has some unusal textures within a convex circle. Sorry for the mediocre photos, My mobile camera has the Specs of a potato. If you need to see more or better photos, just let me know and I will use another camera

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

L.S., Thought it would be fun to share this "chance encounter" I had at a mineral show. The photograph below shows a slab of petrified wood from the Triassic of the Isalo II Fm. of Madagascar. When material from this locality is offered for sale (which happens often and in large quantities), it is usually labelled as "Araucarioxylon" or simply as "petrified wood" (where the latter may actually be better). While most of the wood indeed has an "Araucaria-like" anatomy (see Rössler et al. 2014 for a recent discussion on the nomenclature), I recently was lucky enough to "find" something else. While the left-most photograph may not directly show it, the anatomy of this particular slab is quite different from the common Araucaria-like specimens. I tried to clarify the anatomy by contouring the main structures seen, which hopefully makes visible how this wood consists of multiple rings of perimedular bundles and wedge-shaped structures, showing both centripetal and centrifugal xylem (inward and outward growing regions, per as provisionally indicated by the blue and red arrows). This curious growth form (by modern wood standards, at least) is characteristic for the stems of some groups of Mesozoic seed ferns, such as those from the Umkomasiales order. The best-known genus with this type of anatomy is probably Rhexoxylon (see Archangelsky and Brett 1961), but there are more similar genera, making it difficult to arrive at a more specific identification.

I'm thinking of creating an online 3 D version of my website, but not sure if the image will display on different setups.... I've included a link to an example of a piece of petrified wood (a piece I purchased). I have done some experiments in the field with my setup, I think 3 D in-situ photos would be possible. I've attache a 2 D picture as well. Any feedback appreciated. http://www.safossils.com/petrifiedwood.html Thanks, Walt

Made an incredible discovery at home tonight when I noticed tiny baby dinosaur tracks about only 5.1mm long on a ripple slab I had found. I've never seen baby footprints so small before, so I'm amazed. No wonder I didn't notice them for nearly two weeks after I had found them this month! Since there seems to be a partial adult on the edge it makes me wonder if this dinosaur was walking with its new born baby.
