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.

This piece was found at Quqing, Yunnan of China. It’s Devonian formation. I’d it a segment of pterygotus?

From http://sciencythoughts.blogspot.com/2015/05/yuganotheca-elegans-early-cambrian.html: "An Early Cambrian Lophophorate Animal with affinities to Brachiopods and Phoronids. Lophophorates are animals which feed using a filter called a lophophore, which comprises a number of setae covered tentacles, to extract food from water. The group includes the shelled Brachiopods, the worm-like Phoronids, the minute Entoprocts, and colonial Bryozoans, and has been shown by molecular and embryonic evidence to be related to the Molluscs and Annelids. Within the Lophophorates the Phoronids and Brachiopods are thought to be closely related, with some studies suggesting that the Phoronids should be regarded as a shell-less subgroup of the Brachiopods."

This specimen is about 16cm in length from Guizhou in Triassic formation. Any idea if it's a primitive agnathan?

I believe it’s a feeding appendage. I’ve been told it’s an anomalocaradid feeding appendage, but i don’t remember any of the anoms iv seen having anything quite like that. I can’t remember ever seeing it in context, although feeding appendage definitely seems right.

Good evening folks. I have an unidentified fossil plant from Yunnan (suspect), China and is lacking any additional information. The plant leaf/stem section is 30mm wide x 35mm tall. Hoping someone in TFF knows what it is.

Hello folks. I've been digging through my "unidentified" draw again and came across eight Trilobite requiring identification. I cannot seem to locate my documentation, so, I am humbly requesting your help once again. The information I do have on this Trilobite is it comes from Yunnan, China and is from the Cambrian period. It measures 25mm x 17mm.

Journal of Paleontology, 88(3), 2014, p. 457–474. Quote: "Although the lobsters were interpreted as having relatively durable cuticle, the shrimp discussed herein are characterized by having very thin cuticle that is readily deformed and oriented in a variety of positions. As a result, the description and interpretation of the morphology of the shrimp is, of necessity, a composite of several specimens; however, fine detail of many parts of the skeletal anatomy is exquisite."

My friend found this big concretion like fossil in Quqing, Yunnan of China. Something on the surface looks like a placoderm to me, what do you think?
