    Wheeler Shale Unknown

    Hey guys, I found this last month in the Wheeler Shale in Utah, and I'm at a total loss as to what it is. I showed it to a friend who collects there regularly and he wasn't sure what it is either. He suggested it might be a carpoid or something similar. It's ever so slightly raised on the matrix. Does anyone recognize it? Scale in inches:

    Trace fossil or scour mark?

    I collected this at Marjum Pass in the House Range. The beds are likely Wheeler Shale but almost certainly middle Cambrian. Trace fossil or scour mark? The ruler is marked in centimeters, so an individual grove is about a centimeter long.
  4. I had a bit of spare time today so I thought I'd prep a trilobite or two from my trip around the Confusion and House Ranges of Utah. (See trip report here) I had found this guy in someone else's throwaway pile probably after it came out chipped and subsequently scraped. I didn't think it was worth leaving out in the elements so I brought it home. Here's a before picture. After 4 hours of swapping between dental picks, wire brushes, toothpicks, and various Dremel attachments here is my final product. It's not perfect at all bu

    Wheeler Shale Mysteries.

    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

    Elrathia kingii?

    I recently purchased a 40lb box of shale from U-Dig Fossils in Utah. Mid-Cambrian, Wheeler Shale Formation, House Range, Millard County, Utah. This morning after work, I split a smallish piece & one side had an odd dent, the other had an indistinct, slightly raised shape that sort of looked like a trilobite, so I started trying to find out if it was. This was the result. Using dental picks, a needle in a small pin vice, a # 428 Dremel wire brush (by hand) & another small, round nylon brush (Dremel) in another pic vice... and lots of patience. I think it's most of an Elrathia Kingii min
  7. Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:
  8. Hey hi Y'all, Was looking at some of My trilobites from My last trip to the House range and found something that is not a trilobite. Wheeler shale, mid cambrian. Any help to make an ID on this thing is always appreciated. Thanks. It is 1 cm long.

    Help with udig quarry shale fossil

    Hi everyone, firstly I'll apologize for the poor quality pictures. These Fossil are tiny and it's hard to get a good exposure. These things which are in all the shale I brought back are like rounded objects. They will come out leaving the impression behind. One is 1/8th in and another is about half of that. If any one can help, I'd love to know. On the paper they gave us showing what we can find, there are brachiopods but these seem to all and not the right shape. paper has something called pyilocardia or something like that. Thank you

    Found associated with Elrathia kingii and Itagnostus interstricta trilobites. See field trip report here:

    Itagnostus interstrictus

    Found during a trip out to a hill right adjacent to U-Dig Fossil Quarry. The trip report can be FOUND HERE. This is the largest I've collected. Typical sizes I've found are 3-6mm in length, 1-3mm in width.
  12. Can anyone help identify this soft body? I found it in the Utah - Wheeler Shale formation while searching for Trilobites. I am always keeping my eyes peeled for any soft bodies such as worms, algae, etc. and came upon this after splitting a rock. It is roughly 16 mm long with a body that can be best described as an olive with 2 stalks sticking out the top end. There does not appear to be any missing parts, although this may be a partial body. Evidence of this is the organic/mineral "halo" which can be seen around the body. Also, there appears to be an alimentary canal progressing through the

    Utah Fossil Conundrum

    After many years in Europe where I found the collecting more difficult, I am finally back in the U.S. and have taken my first long collecting trip in years. I was recently collecting in Idaho, Wyoming and Utah and found a few fossils (I think) that have me stumped at the moment. The first is from Wheeler Shale at the Swasey Springs site and I am not sure what it is at all. The area shown in photo is about 2 inches across. The second is from Marjum Formation at Sponge Gully. This is about 4 inches tall. At first I thought "well perhaps it is a sponge", but I have not really be

    Well, i thought I'd show my primitive prepping skills. This is all rather unnecessary as Tony @ynothas already done this thread here and probably better and the pieces shown were kindly donated to me as well. So treat this as a repeat of what Tony does better. Hey ho. So these are the three pieces that Kind Tony sent me. 1. Notice this Elrathia kingii (1.2 cm long) has a break on the anterior margin (cause of death?) .and an upside down Itagnostus interstrictus (5.5 mm) above it and a piece of another to the right of it. 2. This Elrathia (1.8 cm long) has anot

    U-Dig Part 2

    Since my move to Utah two weeks ago I have been dying to return to U-Dig. My wife allowed me to go on one condition, that I would be back home by 3:30 in time for her brothers farewell party as he is going on his Mormon mission next Wednesday. I ended up calling Shayne the quarry owner, explaining my dilemma and asked him if I could start digging at 7:00 am, two hours before the site opened. Surprisingly he approved and I called Bevan. Bevan was going to man the station at U-Dig so Shayne wanted me to give him a heads up. I awoke on Saturday morning at 3:30 am and hit the road at 3:45. I was a

    Elrathia kingii

    Collected on a field trip to U-Dig Utah and prepared at the U-Dig site station. After a light mechanical brush exposed the shale, mineral oil was applied with another brush for a polished finish.

    U-Dig Utah Dig

    Yesterday morning my cousin Matt picked me up at my in-laws in Alpine, UT at 6:30 am and we travelled down to U-Dig south of Delta to dig for Cambrian trilobites and other marine life. It was a three hour drive and we came into the quarry at the perfect time. Robin (Rob), the helper on site brought out some very neat finds including an ammonite hash, ammonite, and an Asaphiscus wheeleri with a green tint to it. Rob guided us to a spot that had been ripped up the previous day by their onsite bulldozer. There were large slabs of shale everywhere for the splitting and we where the only ones out t
  19. Hello everyone, I was looking at my collection of Wheeler Shale Elrathia trilobites and noticed one that looked different from the rest. It's cheeks look more elongated and pointy. Could this be a different species? Thanks, Jay

    What are these protrusions on Elrathia?

    I'm going through a bunch of trilobite fossils I collected at U-Dig Fossils in Utah about 10 years ago to get practice removing matrix. I started with this one because it's only a partial and would be no great loss if I messed up. I'm pretty sure it's an Elrathia kingii but what I don't understand is the protrusion that runs almost the full length of the axial lobe on the left side. It looks like it may have penetrated the animal in life. But it could have been part of the axial lobe that was displaced after death? There also looks to be a similar fragment along the right side of the axia

    Trilobite hunting in Utah

    Looking toward the mountain we hunted, a wild horse watched us Looking down the 20 mile dirt road After a fossil fish hunt in Wyoming, we drove to House Range, Utah to hunt Trilobites at the U-Dig quarry. The formation is Wheeler Shale, 500+ MYA. The drive between the quarries was about 6 hours. Well worth it! The final 20 miles is a dirt road through the desert. We rented a 4x4 truck as we were told we shouldn't attempt the drive down that road after a rainy day. As luck would have it, we didn't get into rain & the road was well graded. (continued next post)

    Caryosyntrips sp. (serratus?)

    From the album: Anomalocaris and friends.

    I have identified this Wheeler Shale fossil as Caryosyntrips sp. (The Burgess species are serratus, but this is much younger and a different location so is most likely a new species). It was thought to be Anomalocaris sp. I have sent this fossil to Dr Allison Daley of Oxford for study. The Caryosyntrips has only ever been found at the older Burgess Shale.

    Splitting Wheeler Shale

    I received a quantity of Wheeler shale as a gift, but I can't figure out how to split it. The Internet has not been very helpful. I am using a flat chisel, but the shale is breaking off in small fragments instead of splitting down the middle. I do not want to damage the trilobites that are possibly inside. Do any experienced shale splitters have any advice?

    From the album: Adventure is an individual thought!

    One of many "hidden quarries" in productive trilobite country. About 15 miles south of the U Dig site. Hard work but with a shovel and tools to split shale, you will find more than you would have expected. Elrathia is the most common trilobite to be found here. Not too far west and you will find Pernopsis, blind trilobites that look like "bar bells". Also some "unknowns" that you need to take home and figure out WHAT it is. Sometimes, multiple complete specimens in the 3/8 inch to 1 1/2" sizes! Camp just below the quarry or look around at loose slabs for trilobites washed down the cliff
  25. Ray Eklund


    From the album: Adventure is an individual thought!

    Many old trilobite quarries to be found. Some are hidden right over a small hill. Some are obvious and alongside the road. Plenty of camping spots. Visit the U Dig site in the area. All of this is just west of Delta, Utah. Before you go, gas up, water up, eat a good meal before leaving town and head to the House Range mountains.
