World's Biggest
It's Canadian! The world's biggest carnivore coprolite is a tyrannosaurid dropping found near Onefour, Alberta. It's two-feet (64 cm) long and 6.5 inches (17 cm) wide - and full of crushed bone. Its final resting place is the Royal Tyrell Museum in Drumheller, Alberta.

Deepest Pile
The Ice Age mammoths and ground sloths that took shelter in southern Chile's Mylodon Cave left quite a mess. Their droppings form a three storey tall mound of dried doo-doo.

Most Beautiful
Say it with agatized coprolite! These permineralized (turned-to-rock) coprolites have beautiful streaks and swirls of red, white, yellow and blue. They're cut and tumbled to make distinctive gem stones for jewellery.

Oldest
The oldest coprolites are about 1.9 billion (that's 1900 million!) years old. The poop is from tiny marine creatures similar to modern copepods. What's amazing is that this poop is the earliest evidence of any kind of the first multicellular creatures on Earth.

Biggest Human Haul
Add another one to Texas' "big" list. More than 1000 human coprolites have been collected from Hinds Cave in the Chihuahuan desert in southwest Texas. These turds were deposited by ancient Americans over the course of about 8000 years. Most of the specimens are about 95-per cent fibre. That's about 15 times the amount of fibre the average American eats today.

Coldest Coprolites
Huge patches of frozen ancient cariboo poo have been discovered in mountainous areas of the Yukon and Alaska. The caribou pellets collected over millennia as caribou used year-round mountain snow patches as a retreat from biting insects. One of these snow and scat patches is as long as ten soccer fields end-to-end.

Best Source of Ancient DNA
It's not fossil bones or teeth. It's coprolites that are #1 source of ancient DNA. This was discovered by McMaster University scientist Hendrik Poinar. He's the son of George Poinar, the ancient insect expert whose research inspired the book Jurassic Park, in which scientists get dinosaur DNA from a Mesozoic mosquito preserved in amber.

Privy Gold
Archaeologists love outhouses. They're one of the best places to find intact artifacts (soft landing). And people threw things (bottles and bodies) into outhouses they didn't want found.

World's First Artificial Fertilizer
Coprolites helped launch the modern era of agriculture. They were among the first phosphate-rich rocks ground up to make fertilizer. The town of Bassingbourn in Britain has a coprolite statue to commemorate this fact.
