Although originally described as an alga, F. gyrata is now regarded by some authors as a coprolite (e.g., Steiner et al. 2005). Taxonomy from GBIF.org. Description and remarks by Chen and Zhou 1997., p. 88 : "Thread cylindrical, unbranchial, with a uniform, flattened width of 1.2mm and a preserved length of at least 20cm. Surface bears a tightly and helically coiled structure. Remarks: This is the most abundant alga in the Chengjiang biota. Most of the thread are preserved within a microturbidite mud layer and show irregular twisting, indicating that the thread was extremely flexible. Specimens probably sank to the bottom from the overlying water column, in a very low-energy environment, before the incursion of minor mud flow.” Restoration by Chen and Zhou 1997., p. 89: References: Chen, J.Y., and Zhou, G., (1997) Biology of the Chengjiang fauna.

Asialepidotus shingyiensis
Crazyhen posted a topic in Is It Real? How to Recognize Fossil Fabrications
Take a look at this Asialepidotes shingyiensis from Yunnan, China. It is a very nice fish. But do you see what's the problem?
-
This piece of incomplete fossil is from Yunnan, China. Same locality with Keichousarus, Triassic Formation. Any idea what is that? It looks like there are broken bones.
-
Hi there! In my excitement to open a box of fossils gifted to me, I mixed up a couple of labels - hopefully someone out there can help me fix my mix-up @piranha The labels are Paleolenus lanlenoisi and Yunnanocephalus yunnanensis - both from the Lower Cambrian of Yunnan, China. Photo #1: Photo #2: Thanks in advance for your help!!!

Vannier et al. 2006 assume that Tuzoia and the also Cambrian genus Isoxys are possibly representatives of the class Thylacocephala. Emmended diagnosis for the genus Isoxys by Garcia-Bellido 2009, p. 1224: ”Arthropod with one pair of cephalic appendages and a uniform series of at least 13 pairs of biramous appendages. Long, narrow body covered almostentirely by a bivalved, very thin unmineralized carapace. Prominent, stalked, spherical to pear-shaped lateral eyes protrude beyond the anterior margin of the carapace. Each valve armed with prominent cardinal spines. Dorsal outline straight or slightly projecting to form a weak to well-developed cusp (small circular node may be present below this cusp) anterior of mid-length. Ventral outline semicircular, weakly preplete (valve is highest anterior to its mid-length) to postplete (highest posterior to its mid-length). Simple perimarginal features (very narrow to more inflated rim). No flattened ⁄ concave marginal features. Narrow to broad doublure may be present. Carapace folded along the dorsal line (valves conjoined by a narrow band of cuticle; absence of articulating hinge). Internally, midgut glands may be present. External ornament may be expressed as uniform micro-reticulation or longitudinal striae. (Modified from Vannier and Chen 2000, p. 311)." Hou et al. 2007, p. 118: “This is one of three Isoxys species recorded from the Chengjiang biota. It is relatively rare and, unlike its Chengjiang associates Isoxys auritus and Isoxys curvirostratus, is known only from carapaces. The thin, elongate, bivalved carapace has a straight spine at both the anterodorsal and posterodorsal corners. The posterior spine is longer than the bivalved part of the carapace. Including both spines, carapace length can exceed 100mm. I. paradoxus can easily be distinguished from I. auritus by the unequal and total length of its spines. I. curvirostratus is distinguished from other species of the genus by having a curved anterior spine (Vannier & Chen 2000). Isoxys is a component of the earliest arthropod faunas worldwide. The genus is known from the Lower Cambrian of Spain, Siberia, South Australia and Southwest China and also from the Lower to Middle Cambrian of Laurentian North America. The ecology of Isoxys is discussed under I. auritus. I. paradoxus is unknown outside the Chengjiang biota.” Line drawing from Garcia-Bellido et al., p. 1224: Identified by oilshale using Hou et al, 2007.

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.

What is this thing? It looks like a platypus worm with spines coming out of its head. It’s from the Maotianshan Shale in Yunnan, China. What is it?

Taxonomy according to Fossilworks.org.

Synonym: †Archotuba conoidalis Hou et al., 1999, †Cambrorhytium sp. Chen & Zhou, 1997 Quote from ‘The Cambrian Fossils of Chengjiang, China: The Flowering of Early Animal Life, Second Edition’: Hou Xian-Guang et al., p. 136: “This species is relatively common with hundreds of known specimens, which are essentially the remains of the tubes of the animal. All of the specimens are preserved as compressed fossils, in which a whitish color, sometimes with rusty patches. No proboscis or other soft parts of the animal have been discovered. The tube is shaped like an elongated cone. Large individuals can reach 5cm in length and 6mm in diameter for the wide opening, with a sharply pointed posterior end. The surface of the tube is smooth and and lacks ornamentation, but a few specimens show sparsely distributed annulations. Parts of the intestine can be seen through the tube as a dark longitunal structure running down the midline of the fossil. Archotuba is monospecific. A. elongata was originally reported as Selkirkia? elongata Luo & Hu, 1999. Chengjiang material recorded under the name Cambrorhytium sp. nov. of Chen & Zhou, 1997 and the species Archotuba conoidalis Hou et al., 1999 are considered to be the same species as A. elongata. A. elongata shows similarities to the other Cambrian tube-dwelling genera Selkirkia and Paraselkirkia and phylogenetic position of A. elongata remains problematic. It was originally assigned to Priapulida (Luo et al. 1999; Hou et al. 1999), but others have suggested that it might be related to cnidarians (Chen Jun-yuan & Zhou 1997; Chen Jun-yuan 2004; Huang 2005).” This species is often found fixed to other creatures, and even clustered together with its own kind in similar orientations. A sessile lifestyle would suggest against an assignment to Priapulidae. However, if indeed they were sedentary like the cnidarians, no tentacles have been preserved to support such a conjecture.

Taxonomy according to Fossilworks.org. Quote from Zhang et al. 2003, p. 447:” The Chengjiang Lagerstätte yields several well-preserved Early Cambrian fossil assemblages (Zhang et al. 2001) from the Yu’anshan Member of the Qiongzhusi Formation in Yunnan Province, South China, consisting of a diverse suite of arthropods (Shu et al. 1995, 1999a; Hou and Bergström 1997; Zhang 1999; Zhang et al. 2000). One of them, small and relatively rare, was only briefly described based on a few specimens (Hou et al. 1991), and repeatedly considered to be a giant protaspis of a naraoiid by many authors (Fortey and Theron 1994; Chen et al. 1996; Hou and Bergström 1997; Hou et al. 1999; Luo et al.1999). Recently this animal was also recovered from the Middle Cambrian Kaili fauna of Guizhou Province, South China (Zhao et al. 1999). Diagnosis for Primicaris larvaformis according to Zhang et al. 2003, p. 450: “Small, protaspis-like arthropod; undivided dorsal shield with a pair of posterior spines and ten pairs of lateral marginal spines; on the ventral side, one pair of uniramous antennae followed by ten pairs of biramous limbs.” Camera lucida drawing of holotype (ELI12001012), from Zhang et al. 2003: Identified by oilshale using Zhang et al. 2003.

Hello partners. I have received several Chinese trilobites, but these two the seller has not been able to identify. I have not found information about them, and I bring them here in case someone can recognize them. The first is from the lower cambric. It comes from the qiongzhusi formation. Kunming (Yunnan). China. with 6 millimeters long THE SECOND IS FROM THE ORDOVICIOUS. SHIHTIAN FORMATION. BAOSHAN. (YUNNAN). CHINA. WITH 1 CENTIMETER LONG. ps: the photos are screenshots of the purchase, my photos do not get better.

This vertebral bone is from Yunnan, China. Any idea if it’s mammalian or dinosaurian?

Here's a specimen I acquired a while back. The worm is quite small (21mm long, ~1mm wide) and hard to photograph but I did my best. The question is, what are those little oval pellet-like things inside (or on) the worm? Its last meal? Parasite? Something taphonomic in nature (I doubt it)? Any ideas would be appreciated! Not sure of the worm's ID, either. I guess either Maotianshania or Cricocosmia (or Paleoscolex?) They're all so similar I'm not sure how to tell them apart. There should be enough detail - looks like everything including the spiny head/proboscis (left end) is visible.
