From the album: Pierson Cove // Marjum Formation Fossils
An uncommon species with a coarse preservation method. Covered in tiny spines, the bug is only missing its right librigena. -
From the album: Pierson Cove // Marjum Formation Fossils
Nice inflated example. B. microps is a truly minuscule species, rarely making it past a single centimeter in length. -

A nice double from Pierson Cove. -

Agnostid right next to the worm fossil. -

Marjum Formation, found this surface collecting after I got sick of working the insanely tough rock. -

Uncommon corynexochiid from Pierson Cove. Partial cheekless molt, but rare! -
From the album: Pierson Cove // Marjum Formation Fossils
Enigmatic fossil from the Pierson Cove. Less prevalent here than at the Wheeler outcrops we explored. -

PC Agnostid with dark anterior spines -
From the album: Pierson Cove // Marjum Formation Fossils
Nice brachyaspidion that split out at home, just needs a bit of work and it’ll be perfect! -

A nice, puny Jenkinsonia from PC prepped out by Jon! -
Hey everyone, I found this ventral trilobite in Marjum Pass, Utah over the summer. I wondered whether somebody could prep it out for me. I'm a student working part time so my budget is limited, but I'd love to talk about what it might cost for somebody on the forum to do this job. Here are some pics:

I just received this "phyllocarid" valve from the Marjum Formation (Middle Cambrian) of Utah. It was sold as Canadaspis perfecta. It measures about 1" long and 3/4" tall. Although I don't have a compass, the angles between the hinge line and both the anterior and posterior margins of the valve look to be less than 100 degrees. Several papers I've read state that these angles are usually closer 120 in Canadaspis. Any thoughts on what this might be?

First of all, apologies for the image quality. I know flash can be pretty horrid but it's all I can do at the moment. Side-views will be found in the following posts! I collected this (probably molted) trilo at Marjum pass in Utah a few weeks ago. The depth of the axial lobe and how the pleurae seem to flare up led me to believe that this specimen is on its back. I only have a pin vise at my disposal and I don't want to ruin a good specimen with the incorrect equipment, but I wondered if anyone has heard of pin-vising Marjum shale. Would you use air abrasion? In that case I will save it for a few years when I can afford it (: Thanks for reading, hope everyone's staying safe!

Went out on a dig near Utah for Modocia typicalis with Gene Boardman one of the site managers at U-Dig. Gene is a really nice guy. He gifted the first trilobite of the day to me (I asked if he was sure and he said he had a few more). We split a lot of rock. A lot of work for a few beautiful bugs. Each image is captioned. Some are out of order. This is the great Gene Boardman. What I admire the most besides his genuine personality and big grin, is that he's a tenacious fossil digger. He kept reminding me to check every rock and to keep splitting it down as far as it would go. Here he has a thin slab of Marjum shale but he was able to find the first trilobite of the day with this fine split method. Really nice guy. The Marjum was not easy to split. It kept fracturing in multiple spots. The overburden was very brittle so we had to get down into the good, red layers. Here we are letting the rock "sweat" as Gene calls it. That means you set your chisels in the rock and let it naturally split and come back later to open up the bench. Lots of hard work. Gene helps run the U-Dig site and is known around the area for his enthusiasm for hunting trilobites and other fossils. The first Modocia typicalis was recovered 2.5 hrs. into the dig. It's small but complete and has some decent features. This is Gene's finest Modocia typicalus in his shop. He did an excellent preparation job. This big Modocia (over an inch) probably isn't a full specimen but has some great features. This smaller Modocia popped out of the same slab as the larger one. You can see it's impression on the left side. Another of Gene's Modocias. Gene gifted this M. typicalis after our days labors. Boy was I happy!

Gene recovered this M. typicalis in excellent condition and gifted it to me while out in the field.

Gene gifted this Modocia to me. Although it's not complete it's a fine specimen with some excellent details. I did gift him a box of fossils from Ohio and Maryland so I'll count this as a trade. These trilobites are relatively rare to find intact and complete. Gene claims one is found every 8-10 hours in the Marjum. The Marjum is brittle and unforgiving. Care must be taken to preserve these specimens in the field.
