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, everyone! Just got a new, greatly improved setup for photography, and wanted to share some of what I suspect are sponges from the Wheeler Formation. I thought a few might be Gogia (an eocrinoid), but I don't think so. I have many such specimens, but these appear to be the most evident. The first couple are the positive and negative of the same specimen. For scale, they are 8mm to 1cmm in size. All of the other pictures of other specimens are the same size. Enjoy! Though trilobites are spectacular, there is much more to the Wheeler Formation than trilobites,

I was recently sent some Wheeler Shale material from the Antelope Springs area of Utah, Middle Cambrian age. Thanks to my good friend Debra @Paleome It's all rather splendid stuff, not the usual Elrathia kingii or Itagnostus interstrictus, but a selection of wonderful more unusual things. But what about this one? A trace fossil of a burrow? Some sort of sponge or algae? Any help will be greatly appreciated, as always. Thank you. The inside of the object is an orange brown colour, while the outside and surrounding regions are sort of beige. It reminds me of some

I just received a new shipment of matrix/prep material from the Wheeler Formation of Utah this afternoon. What should be looking at me from within the box is THIS! It is huge, about 3 inches wide by 5 inches long, very smooth and flat, with a well-defined margin to it. I don't yet know if I have the other side to it, yet. First, I thought it might be the remains of a jelly, but I don't see any structures within, like concentric rings or radiating lines. Then, I thought maybe it is a cephalon shield or carapace of a very large phyllocarid, like Branchiocaris. I am

I have just returned from my first visit to a new fossil locality in the Northern Territory, central Australia. The location is around 400km north-east of Alice Springs along some rough dirt roads and once reached, runs for about 10km along the side of the road. When visiting the location today one finds themselves in the very center of Australia and a landscape of flat desert and scrub land, about as far from the sea as possible. In the middle Cambrian the site was very different and home to a vast shallow sea filled with ancient life. Arriving in the late afternoon we set up camp

Hi Everyone, I've recently returned from a weekend trip to a fossil site in central Australia. The location contains siltstone laid from the ancient ocean once in the middle of Australia during the middle Cambrian. Both John R. Laurie and Dr P.D. Kruse have completed work on the site and have some publications accessible online. Along with a good collection of trilobites I came across a number of what I believe to be stromatolite fossils. The first image (1.1) was found on the way to the location about 150km before we reached it, the road cut through a much lighter shad

I noticed this thing on a plate of hyoliths I received from the Middle Cambrian Zhangxia Fm, Shandong, China. It kind of looks like a carpoid to me, but it may just be a suggestively shaped fragment of some other fossil. Any thoughts?
