HI! New member here on the Fossil Forum from Sydney, Australia. My son wanted to find some marine fossils a couple weeks ago, so we went to Ulludulla's Permian aged (kungurian) Gondwana fossil coast. I need ID on the poorly preserved largest fossil in the middle (ignore spiriferid brachiopod on top right). Note this fossil is part of the Wandrawandian Formation (Shoalhaven group), south of the Sydney basin, Ulludulla. Thank you in advance for any help you guys can provide because I'm no expert.

As the temperatures are heating up in the desert I'll be moving more into the high country collecting. This will bring me to formations bearing ammonoids. My understanding is I'll be finding versions of goniatitic ammonoids as opposed to true ammonites that didn't emerge until the Jurassic? I'll be primarily hunting in upper Pennsylvanian or lower Permian formations. These will be new formations to me and difficult to determine the age. There are no stratigraphic maps for the areas I'll be searching to guide me. Hopefully I'll find additional marker beds or fossils that will help date the formations and make them easier to find by association. It appears that obtaining complete specimens will be rare as the best preservations seem to be in dense limestone. Here are a few remnants. Is it possible to discern the species from these limited portions? Also, is there a good link to understanding and being able to recognize ammonoids from the Pennsylvanian to Permian? From what little I can read from research papers for our geology they have not been studied well and there is little reference to them. The specimens range from the smallest being 150mm to largest being 200 mm (6" - 8") in diameter. I feel the preservation is generally nice but finding complete specimens will be pure luck. Thank you for any beginners tips and guidance. Kato

Hello, now that I have time, I decided to create a small guide on how to recognize fake, painted and carved amphibians from the permian of europe. In this guide, you'll find examples of fake or heavily restored, or painted amphibians compared to real ones, and you will also learn some of the most common red flags on them. I hope you like it and that it will help many people not falling into amphibian traps ! Enjoy ! 1.0 Apateon pedestris (Credits: online auction site) This was done in the same way as your toddlers' paintings on the fridge (if you have a fridge or a toddler). The "bones" are probably drawn with a pencil and the preservation of the skin shadows is nothing more than some clear paint. If you look closely, no bones are evident. Here are some good examples, the first being from my collection. Now compare this to the previous one. Horrible! 1.1 1.2 Example of a perfect skull. See the difference? (Credits: Thomas Billert, Steinkern.de) Heres an example of a sideway skin shadow. Skin shadows should always follow the bones whith a bit of distance, and should feel stony and look not like clear paint. 1.3 (Credit: online auction site) 1.4 Perfect skin shadow, sligthly preserved (Credit: online auction site) 1.5 How a skeleton of Apateon should look like (Credit: Jürgen A. Boy) 2.0 Sclerocephalus haeuseri (Credits: @Amontano) That's partially real, but not, not, not much of it. The paper shale it was found in is not known for creating great skin shadows and preserving bones and limbs. That's why many amphibian fossils found in it look the same. To make it look like if they still have all their skin, bones and limbs, in most cases they are painted or, for 3D preservation, reconstructed with modeling clay and then painted to match the overall look. 2.1 Here is an example of a completely real and well prepared example. Compare this with the other one. Big difference, isn't it? (Credits: @Vertebrate) 2.2 How a skeleton of Sclerocephalus haeuseri should look like (Credit: Alamy.com) 3.0 Branchiosaurus petrolei (Credits: online auction site) These ones from france are mostly real, but youve probably guessed it: fake limbs and skin shadows ! They look like stick figures ! These were also painted whith clear paint, and sadly, they cover most of the remaining bone structure. Heres an example of another painted one, which i thougth looked to funny to omit. Three back legs ! Two real and great preserved, one fake painted stick. The head on this was also heavily painted and is non definable. 3.1 (Credits:online auction site) And here is an example of a 100% real one from my collection. You can see the completly different head shape, the toe bones on this are not preserved, but i think, you can spot the difference. This above could also be called "how to ruin a great fossil whith paint". 3.2 Example of a real one from my collection. 4.0 Discosauriscus pulcherrimus (Credits: @RobFallen) Well, this migth be a complete drawing on rock. If you look closely, you can see that the bone bend whith the rock, and its also very suspicious that the left foot is bend in, and not broken off. You can quoestion yourself, what was first: the rock, or the amphibian ? But this is a tricky and relativly good fake, many ones out there. 4.1 (Credits: online auction site) This is an example of a 100% real and 3d preserved one, really expensive. So you can compare them again, and you'll notice a difference again, mostly in the skulls. 5.0 All points and red flags together for all amphibians, also that were not featured in this guide 5.1 Skin shadows, if they dont match the overall look, shape or look painted, theyre in most cases really just painted whith some clear paint. 5.2 Bones, if most of them in one specimen dont match the shape they should be, or are dark and bend whith the rock, or not 3d, theyre mostly pencil drawings. 5.3 Skulls, if they look suspicious, google the species you're looking for and compare the results to the skull. If they look completly different and the one you think looks suspicious lacks in detail like jaw, teeth, or many bones are wrong, better run ! 5.3 Vertebras, in some specimen, the vertebrates are carved or reconstructed whith modelling clay. Carved ones are mostly circular or a square, and lack in structure and connection to the other ones. There are big, unnatural gaps in between them. The reconstructed ones are more tricky, but rarer to find. To recognize them, you should check the connection to the stone, or the other vertebras. Something looks wrong, better stay away ! 5.4 Toes, if they're missing, they're mostly just painted. You can recognize them by a different color, shine, the toe bones missing, and also that they're bending whith the rock. 5.5 Ribs, if they're straigth and not bend, thats mostly a red flag. Or if theyre bending whith the rock, better be carefull. 5.6, no red flag, but if you think theres something wrong about the specimen you want to buy, just wait, use that guide, or do the research yourself. Many fake amphibians are easy to recognize, even if you're not that experienced, and if you're unsure, just post it in the Forum, we have so many very experienced members here, they'll help further ! Have i something missed that i should mention or have you extra wishes ? Could ive done something better or should correct something ? Let me know !

Hi! Awhile back i sorted through some Comanche county Oklahoma permian matrix. li’ve got a lot of pieces needing i.d. But I thought I’d start with this one. Its right at 5mm long in some ways I think it’s a tooth but I’m not sure. Anyone have any ideas? Today I was trying out a new magnifying device so I thought this was the perfect time to ask! Please ignore the date.i havent reset it yet…
