A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Hello! I bought these Cambrian soft tissue fossils supposedly from Yunnan in china off of online auction site. I won them in a bid for suspiciously cheap. They seem real to me, but I’d be interested in confirmation of that. I’m also interested what you guys have to say as to what these are. Thanks! One is listed as Naraoia spinosa, the other, fainter one is listed as Vetulicola.

I purchased this as a supposed Silurian Megalograptus from Yunnan a while back. The seller gave me additional information that it came from the Devonian Cuifengshan Formation in Qujing, Yunnan, China. However, the genus Megalograptus is Ordovician in age. I'm not really familiar with eurypterids, so maybe it's not even a sea scorpion. It certainly looks like some kind of invertebrate though. But maybe it's just indeterminate debris.

Hello, Could I get an identification for this fossil from the Cambrian of Yunnan, China? It was described as a "Chancelloria", but I don't know if that specific genus is described from this locality and the sclerites aren't star-shaped. It may be a related Chancelloriid, and it seems there are several described from China. My best guess is something like Allonia: https://www.researchgate.net/publication/316342674_Chancelloriid_Allonnia_erjiensis_sp_nov_from_the_Chengjiang_Lagerstatte_of_South_China http://www.paulselden.net/uploads/7/5/3/2/7532217/zhaoetal2018small.pdf I wish I could get higher-res photos of the sclerites but unfortunately I don't have a camera besides my phone. PS. Also, what could that grey+orange conical object next to the Chancelloriid be? Part of a trilobite genal spine?

Taxonomy from Fossilworks.org. Etymology: From Luoping County (Yunnan Province, South China), where the new fossiliferous site yielding these specimens is located; dedicated to Lev Semenovich Berg (1876—1950), a famous geographer and biologist, member of the Academy of Sciences of the USSR, for his great contributions to the study of fossil fishes. Diagnosis for the genus from Sun et al. 2009, p. 462: “Fusiform to deep fusiform polzbergid. Preopercular sickle-shaped, with a short infraorbital process, a vertically oriented dorsal region and an expanded, anteriorly curved, ventral one. Premaxillary, extending antero-dorsally to the maxillary for at least 2/3 of its length; thin procumbent anterior teeth. No field of modified scales at the base of anal fin. Caudal fin with four or five epaxial rays." Diagnosis for the species from Sun et al. 2009, p. 462: "Medium-sized Luopingichthys, with a fusiform body. Six teeth borne by premaxillary, three or four by maxillary and six by dentary. Coronoid(s) present; skull bones heavily ornamented with tubercles, short ridges and small patches of ganoine randomly arranged. Ornamentation on scales reduced to faint longitudinal ridges giving rise to a posterior serration; mid-dorsal ridge scales well differentiated. Stout fringing fulcra on dorsal and anal fins. Caudal fin with rudimentary lepidotrichia and four or five epaxial rays." Drawing of the skull from Sun et al. 2009 (scale bar equals 5mm): References: Z. Sun, A. Tintori, D. Jiang, C. Lombardo, M. Rusconi, W. Hao, and Y. Sun. 2009. A New Perleidiform (Actinopterygii, Osteichthyes) from the Middle Anisian (Middle Triassic) of Yunnan, South China. Acta Geologica Sinica 83(3):460-470.

This skull is 24cm in length, it's from Yunnan of China, Any idea if it belongs to a marine reptile, not icthyosaur? And if it's a complete skull?

The photos below show two juvenile/hatchling ichthyosaurus species from Yunnan, China. They are from two different localities but are close by. As they look quite different, are they different species? And any idea what species they are?

Hello, I just got this supposed Anomalocaris fossil from Yunnan of China, Cambrian in age. It's about 1.5cm length, and I belive a section from the end of an appendage. I was wondering if someone could determine a more specific species ID for it? Hopefully my phone's camera is enough to show the details. The specimen has quite clear preservation of the ventral spines, as well as their auxiliary spines coming off the front and back, and based on that I am thinking something like Anomalocaris kunmingensis (https://www.researchgate.net/figure/Anomalocaris-kunmingensis-sp-nov-from-the-Guanshan-biota-Yunnan-China-a_fig2_257689210/amp). But of course I don't know what I don't know. Thanks.
