Cretaceous era turtle poop? Fossil cast of an intestinal tract? Strange ironstone nodule formation? The science is still out on just what exactly made these sideritic "coprolites"... but they certainly look like — well, we think you can tell. 💩

These specimens come from Early Cretaceous deposits in Central Madagascar and date back 100,000,000 years. While their formation is still up for debate, we've still had quite a bit of fun around the office with them and you can too!

For April Fools' day weekend, every cart over $25 is eligible for one small "coprolite" for free! Orders over $75 can upgrade to a single free large sized specimen!

Small: 0.5" to 1.0"

Large: 2.0" or longer

Please Note: All specimens ship in a bubble wrap bag with an included information card. They do NOT include a riker display case as they are meant for public 'display'.😂

It's not a trick! Here's how it works:

1. Fill your cart to the desired size. ($25+ for free small poop, $75+ for free large poop)

2. ADD one Sideritic 'Coprolite' to your cart.

3. See the savings added automatically at checkout!

The $25/$75 threshold is based on the product total in your cart minus tax, shipping, and of course the "poop". Also, you can buy more if you like, but only one will be discounted.

Sideritic "coprolites" will only be available until Monday, April 3rd, 11:59 PM EST, so come get them while the April Fool's Day weekend is in full swing!

ℹ️ VERY IMPORTANT: We'd love to add this item magically to your cart but CrapGPT™ hasn't been enabled on our prehistoric shop just yet. Maybe some day we'll have an all-knowing AI dedicated to coprolite curation, so until that day comes make sure to add the specimen before you checkout.

When searching for information on long extinct creatures, the evidence scientists are faced with is both scant and contradictory. This particular specimen is one such example.

The exact nature of this item is still unclear. At first glance, it appears to be a piece of fossilized dung, matching modern turtles. The presence of iron has given it the classification of a "sideritic coprolite." However, an absence of food remnants suggests it may in fact be a trace fossil cast of an animal's intestinal tract, called a cololite. Some geologists reason that it could even be an unusual geologic formation rather than a fossil at all.

It's not often we find something that stumps us and other researchers. That's why we're pretty excited to share these! Based on the most current findings, we're leaning to the side of geologic formations, but if they turn out to be true coprolites then you can count yourself as one of the lucky folks who got a free fossil before it was cool! 😉
