  1. Hello everyone! Been almost 2 years since I last visited that site and left in situ a nice multiblock. I was thinking again and again @taj reply and tried to correct that mistake. However, every year the site seems to be less accessible and there are rumors that it's forbidden to search there for fossils due to the proximity of the archeological site of the theater, regardless the fact the outcrop is located within private land. Nevertheless, last Saturday 13/11 we visited the place with a friend. Visited 3 possible outcrops without much results. 1. Carnian exposure with partially pyritized ammonites - overexploited, zero finds. 2. Ammonitico Rosso quarry, no finds but for some slices on marble blocks. 3. Around the theater, near that private place. One nice slice of the Rosso early Jurassic quarry. 100kgs of boulders collected in order to be cleaned. This outcrop has very high density of fossils, due to the absent of sediments, leading in amazing multiblocks full of ammonites, nautiloids and orthoconics. The obvious characteristic of this formation is th presence of Mn oxide, which gives this lovely dark brown/rusty color. Smaller blocks were also collected. Presence of fossils indicate high possibility to find more after abrasion. Before leaving, we visited the museum and bought some prepared ones. You can see how packed are. I tried to find another exposure of Hallstatt facies so I had to find a map, which does not exist online. Found a governmental library and bought it! Next Saturday 20/11 we visited again Epidaurus area. Using a ruler, I put all possible outcrops on my phone, so we were prepared. Unfortunately, all these outcrops were not accessible or altered due to agriculture, buildings and so on. Out of 13 visited locations, none gave fossils. We found another Ammonitico Rosso, but the quality was poor due to tectonic dynamics and extreme deformation. Sunday 21/10, a third visit to the place with another friend. We started locating an outcrop with Miocene gastropods. Near that place, we found another site with some Cretaceous imprints of Pectenoids Then we joined with another guy and headed to search again in that overexploited locality. My friend found a partial Carnian ammonite replaced by jasper and gave it to me. I don't keep partials anymore, but this is really beautiful and rare. The same guy found a nice 4-5cm Johannites sp laying on the ground. It was steinkern but still lovely! Moved further to explore the place a little more and we found something like stromatolites, composed of Mn oxide, limestone of the same fossiliferous site around the theater and possibly, ammonites with complete replacement with Mn oxide.

    Xinpusaurus sp., a Thalattosaur

    From the album: Vertebrates

    Not an Ichthyosaur but an unprepped Thalattosaurus (Xinpusaurus sp.) from the Falang Formation (Triassic) of Guiyang, in Guizhou, PRC. Xinpusaurus can be easily distinguished from an ichthyosaur like Mixosaurus by the extreme overbite: The upper jaw is almost twice as long as the lower jaw. Will need a lot of prep work. Length ~ 60cm
  4. Last week I had the chance to go for a short fossil hunting trip to the area called the Polish Jura – famous for limestone formations, which take several fantastic shapes and have their very own names. Here are some instances: The camel The Hercules club The Trolls It’s also the area with numerous stone castles from the 14th and 15th century – the are located along the so-called Trail of the Eagle's Nests Here are some examples: But my main interest were of course fossil sites. First we visited the so-called Karniowice travertine – academic description says: “they form several lenticular bodies (up to more than 10 m thick) in the lower part of the Permian conglomerates and volcanic tuffs, discordantly overlying the Carboniferous sandstones. Light-grey travertine is locally highly porous or cavernous. It is formed of sparry calcite containing dispersed chalcedone aggregates and impregnations of iron and copper sulfides.“ According to the description it was supposed to be the locus classicus of Dendropupa zarecznyi – one of the oldest gastropods. Nowadays it looks like this: We brought home a few pieces of the rock, but no Permian gastropods (or anything else, for that matter), in them. They just have really fantastic shapes The second location en route was Płaza quarry – the Triassic site I have already visited before. The place didn’t change much from last time: except that there were very little fossils available, mainly brachs and crinoids: I found these two fossils – do you think the white stuff are pieces of bones? The other Triassic quarry in the area was unfortunately turned into a shooting range and is no longer accessible The next day we went to Tarnogórski Canyon – which is a former dolomite mine. It’s quite big: and a bit overgrown not to mention a little lake in the middle We searched the rubble for quite a time, but again – only pieces of crinoids: After such a disappointment, we went to see the Black Trout Adit, which is one of a few Unesco sites in Poland. It’s the only still operating drainage adit in Poland and one of the longest underground boat flows in Europe. We went 30 m underground and then had a 600-metre “cruise” in metal boats: When we emerged back to surface, we decided to stop by the Błędów Desert – yes, we do have a desert in the middle of the country The Błędów Desert is actually Central Europe's largest accumulation of loose sand in an area away from any sea, deposited thousands of years ago by a melting glacier. The aerial view: The next day we started from visiting the former capital city of Poland – Kraków: the home of the Wawel Dragon: Then we stopped at the Jurassic Mirów quarry: We were hoping for an abundance of ammos, however there were not so many as in the nearby Niegowonice and several of them partial and very flattened: They usually are very small: Nevertheless, we managed to find a few things: Plus a mystery fossil? The last stop was Młynka quarry – also Jurassic: The most interesting place however was a little ravine next to the entrance – with Callovian rocks: which turned out to be full of goodies: And the cherry on top – the crab That's it - thanks for reading, I hope you liked it

    Found with Keichousaurus

    This piece is found along with Keichousaurus in Yunnan, China. That is, it’s Triassic. Any idea what is that? The “spines” measure about 10cm in length.

    Triassic fossil?

    Triassic scute, shell or paper weight? Found roadside with mixed road stones in NJ midway between Flemington and Lambertville Rt 202. This is part of the Newark supergroup sedimentary rock deposited during the Triassic period. I can't put this down because it feels biological not geological. All help greatly appreciated. My first post.

    Coprolites

    I’ve moved up to the higher levels of my property where I’m finding bones and coprolites. Still hoping for a big score of a full skull.
  9. I got out again to gather a few small specimens of pet wood. Found in the Triassic of the Newark supergroup deposits in southeastern Pennsylvania.
  10. Hello! I am assisting a friend identifying this tooth. He found it in Anisian limestone and so far has not managed to find any further information, since there is not a single publication. The environment is marine, since there are shell imprints, without any shell preserved, so he assumes it belongs to a fish. Another friend said that it might even belong to a reptilian and the teeth have crushing form. It's size is around that of a dime, maybe slightly larger. Any help would be appreciated!

    Unknown triassic spine/bone

    Hi! I've recently acquired unidentified fossil. It's from triassic location in Silesia, Poland. Can you give me some ideas on ID?
  12. Vaderlimulus - 245-Million-year-old Horseshoe Crab Fossil named after Star War’s Darth Vader. New Mexico Museum of Natural History & Science First Triassic Horseshoe Crab Fossil Found in North America, SciNews The paper is: Lerner, A.J., Lucas, S.G. and Lockley, M., 2017. First fossil horseshoe crab (Xiphosurida) from the Triassic of North America. Neues Jahrbuch für Geologie und Paläontologie-Abhandlungen, pp.289-302.

  13. Bought this piece at a Rock and Mineral show and according to the specimen labels that were included with the specimen. It has passed through at least 3 different fossil dealers. Each one stating the following information: Crocodile Scapula Locality: San Juan, NM, (USA) Now I suspect this piece is from the Triassic time period and could possibly belong to a large Temnospondyl amphibian and is a skull fragment not a scapula. Does anyone here recognize the patterning and thickness change enough to give an educated guess as to what it might actually be from? Also, the glue attached to the specimen is fairly thick and hard. Any suggestions regarding how to remove it without causing harm to the fossil? As you can see my attempts at trying to pick off the glue, takes the surface of the fossil with it leaving an annoying white spot. I may have quickly tried acetone if I remember correctly but nothing happened.

    Teeth and bones

    Hi, I was wondering if this could be a Pachystropheus bone? Although it is damaged, it looks similar to pictures of Pachystropheus femurs, could it be a femur? It measures 4.5cm. There's a tooth next to it, the closest possiblity I could find was Ichthyosaur, but I couldn't find anything that similar, so could this be an Ichthyosaur tooth? On the other side, there's some other things. I think the larger tooth could possibly be Severnichthys, and one slightly lower down to be Lissodus minimus I'd appreciate any help, Many thanks

  20. Here is the description of a new welsh theropod Pendraig milnerae. Found in the 1950s in the same fissures as pantydraco, the “new discovery” is a type of coelophysidae and it had laid undiscovered in the drawers of The Natural History Museum in London. https://royalsocietypublishing.org/doi/10.1098/rsos.210915 We are on a roll with Welsh dinosaurs: Megalosaurus (Zanclodon) cambriensis Pantydraco cauducus Dracoraptor hanigani Pendraig milnerae And not forgetting the Triassic mammal Morganucodon watsoni

    Paleontologist visit

    Had a four day visit from Spencer Lucas and Hendrik Klein to study my track finds. Lots of photography, made tracings of the tracks. They took a few truckloads of slabs for the New Mexico Museum of Natural History and Science and will be coming back to collect the large trackway. It was a fascinating week.
  22. A number of collectors are very interested in Triassic Dinosaur tooth material, however, lots of misinformation exists, partially because little is known and dealers want to sell product. My knowledge is very limited so I tried to put together an assemblage of current information that has been published so that we can all become better versed on this topic. I'm not saying its complete but its the best I can do with my limited knowledge. Most technical papers on this subject are outdated, difficult to read for a novice and not complete enough. Fortunately a recent, legible paper was published in 2015 by Heckert & Lucas that has helped me. I've tried to extract the pertinent information, associated with teeth, since that what most collectors are interested in. First let me get on my sandbox and say that we should NOT assume that what is being sold is accurately described regardless who is selling it or how much you like a dealer. Very little is known and even less is described. If a seller insists what he has identified is accurate, have him show you the technical documents that supports his diagnosis. There are a number of theropods and archosaurs in these assemblages that have serrated teeth so identification is difficult. Triassic dealers similar to those in the Kem Kem which label everthing Spinosaurus like to label everything Coelophysis. Just be cautious..its your money. Almost all the teeth you see sold come from New Mexico so I will focus in that region. A Map of New Mexico with the Triassic outcrops shown below as well as the associated Counties. The numbers correlate to the stratigraphic formations shown below in Figure 4. Figure 4 The Zuni Mountains in West-Central NM are from the lower Chinle Group (Bluewater Creek Fm) and contain Tetrapod fossils amphibians and phytosaurs and aetosaurs. Dinosaurs are possible but nothing is diagnostic. Faunal List of the lower Chinle Group Zuni Mountains Northern/West Central New Mexico has yielded some of the most interesting Vertebrate Fossils most associated with Coelophysis at Ghost Ranch. Included in this group are the Petrified Forest and Rock Point Formation of the western counties. Chindesaurus bryansmalli, Tawa hallae and Daemonosaurus chauliodus are considered valid a dinosaurs in the Petrified Forest Fm. Coelophysis bauri is valid from the Rock Point Formation. Faunal List of the Petrified Forest and Rock Point Formation - Key on this list is Coelophysis bauri in the Rock Point Fm Northeasten New Mexico (Bull Canyon and Redonda Formations). Heckerts 2015 paper comments that dinosaur fossils remains are rare in the Bull Canyon Formation. The coelophysoid Gojirasaurus quayi has been described but its taxonomic placement is uncertain. Herrerasauridae tooth fragments have been found but nothing has been assigned to a taxon.

  23. I will trade these fossils for one well preserved European goniatite or European triassic ammonite (specimen with 5 to 8 cm preferentially) because that kind of specimen is lack in my teaching collection. Note the Anorthopygus orbicularis is not a common species and, apart the incomplete test, has an exceptional detailed preservation, rarely seen. Best regards, Ricardo Traded

    Tooth/ plate? I.d Help please.

    Hi, Thank you all for the help with my shark spine I.d yesterday. I was very pleased to finally find our what it was! Today I was looking over some other large pieces of bone bed from the same trip to Aust cliff, and I had a very pleasant surprised when I broke it open. I think it's some sort of tooth, it's large around 5cm in length. Is it from a shark as it was near to the area I found the spine? Any help would be appreciated. Many thanks
  25. Hi, I'm very new to this and have had a couple of trips to Aust cliff uk recently. I hadn't really found much but today I found this tooth/bone? I have tried a little of my own research and have hit a dead end. I think it may be ichthysaur but I'm not sure if it's a bone or a rather long thin tooth. It appears to be hollow.Could anyone help me with an I.D please? Many thanks 20210921_213640.heic 20210921_213649.heic 20210921_214010.heic
