Not just teeth and shells: my fossil collection also includes trilobites, the real protagonists of the Palaeozoic era. The first is a beautiful specimen of Morocops ovatus. Detail of the cephalon area:

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,

Here are images of the 6 honeycomb pattern patches found in my Wheeler Formation collection. First image: 1 mm long Second image: 1mm long Third image: 1.5 mm long One image missing - couldn't get to focus. Fourth and Fifth images: 2.5 mm long. These are facing images of each other - original fossilized and impression - same specimen. I tried my very best, but images are still a little fuzzy, despite higher magnification.

Is this tiny trilobite from the U-Dig Quarry near Delta Utah a Brachyaspidion microps or is it something else? I realize that the pygidium is covered but I don't want to expose any more of the trilobite because I know that it would pop off the shale. Thanks.

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 gone through 200 pounds of Wheeler Formation and found only 5 of these (2 are the original, and the impression of one specimen). I must have missed the impressions or originals of the others. They are difficult to spot. They are honeycomb structures, almost microscopic patches, just sitting on top of, but firmly attached to, matrix. These patches are not any bigger than 3mm at their longest dimension. Only one of them is that big, and they are all roughly circular or oval in shape, no boundaries, no distinct edges. The others range in size from 1mm, to 1.5mm, to 2.5mm i

I found these (almost microscopic) honeycomb patches just laying on top of matrix. They are not attached to any trilobite, but what else could they be? Molted off? Sorry, I tried to take photos of them, but the detail is just not coming up. They are perfectly crystal clear when viewing under the stereoscope. I probably need a better camera. Will try later if/when I invest in something better. Has anyone else found tiny honeycomb patches in wheeler material, not directly associated with trilobites? I am finding both original fossilized and their impressions. I

Ok, several more photos. Now, these strips of oxidized material also have those very tiny filamentous fibers running along their length in the same direction as the strip, somewhat like the grain you see in wood. These may be degraded specimens, with only a few single fibers left. Some have many more fibers per square cm. Remember the oxidized hash (yellow/orange) I showed you previously which is just filled with these fibers? Maybe this particular stuff is actually a clump of algae, and not necessarily just tracks. Maybe the strips without fibers, but instead with ot

I just managed to find most of a frond of Margaretia dorus. Usually, it is represented by ribbon-like strands with tiny fibers running along its length, and frequently iron-oxidized. See photos of posts Ichnofossils, Algae, or Something Else, parts 1 and 2, under Fossil ID. This particular specimen (original fossilized and impression) is fairly three dimensional, and carbonized like the trilobites from this formation. Note the oval holes (pores?) running along its length! Margaretia dorus was originally thought to be an alcyonarian coral, then a green algae similar

These are very tiny, delicate, fibrous/filamentous structures which are most commonly found within an iron-oxidized (? yellow/orange tinted) hash. They are probably part of something bigger, like maybe the fibrous structure of highly degraded algae. These are really hard to photograph with what I have. Again, 3ach circular shot 9mm+wide.

Hello, all! It will take me some time to set up, as I need to get more camera equipment for my stereoscope. I have some very substantial collections from the Wheeler and Florissant. I have been able to identify most of the critters from both (and I'm not finished yet). I have some great books, as well as a number of articles and links concerning these sites, but especially with regards to the Wheeler, I have found some rather puzzling remains which are enigmatic to me, but hopefully not so obscure to others. These are things which I have never seen described, il
