Dig-Dig #8: U-Dig Fossils, Utah

Delta has a big green park in the middle of town. A picnic table was the perfect spot for a quick breakfast. Not so quick that we couldn't enjoy our espresso, of course. We were looking forward to a day of fossil digging, out in the Utah desert.

We followed the clear instructions to U-Dig Fossils, about an hour west of Delta. The dark "C" shape to the right of the dirt road is the quarry.

A smattering of wind and rain-damp shale made a refreshingly cool start to the morning, but the sky cleared quickly. By the end of the day we could feel the heat radiating from the black rock.

Aya got right to work, splitting slabs of soft shale with the chisel end of a rock hammer.

What's inside?

Trilobites! Extinct sea-bugs!

The rock splits at all kinds of unpredictable places, quite unlike the fish fossil site in Wyoming. Hearts were also broken many times as one hit too many resulted in unrepairable smithereens.

But there were many sweet victories!

This little sea bug was lost for millions and millions of years until... now. Each time a layer peeled back to reveal a treasure, it was like a sudden connection with an extinct era; a time capsule, opened at last to reveal a ghostly memento mori.

Yet still lively! This, our biggest find, popped out of its carbonite and disappeared into the rubble around us, leaving us with only the negative impression. That could mean two things, but it only means one.



Here's one that came out of its hiding place with a gentle poke from our new shale-splitter (old paint-scraper).

Aya came prepared with a carrying-case, which she managed to fill with trilobites and other small fossils. Bevan, the very friendly and educating host of U-Dig Fossils, helped make the day even better with his gentle guidance and advice.


Some of the ones that managed to make it home. We are going to take our Dremel tool to them and polish them up a little, as demonstrated by Bevan.

Dig-Dig #5: Fossil Safari, Wyoming



The long drive of the previous day paid off in that we were within a couple of hours of the next destination: Fossil Safari, near Kemmerer, Wyoming. The white spots on the map below are the actual quarry sites. Three huge antelope, looking very African, skipped across the dirt road during the last mile.

This was really, really fun. The big slabs of rock pop open with a satisfying, dry crack after a few whacks with a hammer and chisel. By carefully pursuing a split along the edge, you can peel off sheet after sheet like thumbing through a book with very thick pages. The fish are all within, having been gently pressed like flowers over millions of years. Revealing them is truly an exciting moment.

One of Aya's early finds: a little herring, previous tenant of the ocean that was here before the desert came.

One classroom from our little school of petrified fish.

Chris, the very friendly, helpful and informative host, used his robotic arm attachment to cut our bigger finds into transportable pieces.

This caused a stir. One of the regulars, who hunts for fossils to sell, cracked open an average-looking slab to reveal this monster. Looking at Fossil Safari's website, we think it might be a mioplosus, but that's only because we think we know what we're talking about and we don't. The arrangement with the quarry is that you get to keep smaller, common fossils while they keep the big, rare finds. This one was instantly claimed by the quarry, which might have put a bit of a damper on the elation the finder felt at the biggest hit of his career.

Here's a video of Keith splitting a large slab to reveal...




Here are some of the larger, complete ones that we brought home:
The lower piece was part of a "mortality layer" where it appears that many fish died at about the same time, probably due to a landslide or other natural disaster. There were eight whole fish and a few pieces on this one slab, which we cut up for transporting.

A fantastic double-sided fossil, with the split going right down the center of the fish. Perhaps history's first kipper.


This, our largest one is still partially covered by a fine layer of rock. We will use a Dremmel tool to gently reveal its petro-ichthystic glory.

Dig-Dig #1: Road Trip

Back in 2003 we went to Ica, Peru, and had our first taste of fossil hunting under the expert direction of Sr. Roberto "Penny" Cabrera.

We piled into his specially-equipped pick-up truck.

We camped on the desert floor.

We searched for fossils.

We found whales...

... and shark's teeth.

If it can be said that we have the fossil-hunting bug, then that trip was the vector of our disease, eventually leading us to research places in North America where we could dig around in the dirt for surprising items of questionable value.

This August, we succumbed to a full-on relapse and drove almost 5,000 kilometers in search of very old fish, extinct sea-bugs, and shiny pretty things.

Here is a link to our route on the ever-wonderful Google Maps.
