Description
Offered here is a 100% genuine Dinosaur Coprolite (fossilised faeces) from the world-famous Morrison Formation in Colorado, USA, dating to the Jurassic Period, approximately 150 to 155 million years ago.
This remarkable specimen is a naturally preserved piece of ancient biological evidence—dinosaur dung that has turned to stone over millions of years. Known scientifically as coprolite (Greek for “dung stone”), these rare fossils give palaeontologists direct insight into the diet and digestion of prehistoric creatures.

What is Coprolite?
Coprolite is fossilised excrement from prehistoric animals. Unlike most fossils which are hard tissue (bone or shell), coprolites are the mineralised remains of soft biological waste, preserved over time through a process called permineralisation. Minerals like silica, calcite, and iron infiltrate the dung, preserving its shape, colour, and sometimes even the content!
This coprolite originated from a dinosaur species that roamed the lush Jurassic landscapes of North America, possibly a herbivorous sauropod or a carnivorous theropod. Fossilised dung can be surprisingly colourful, ranging in hues from deep browns to reds, greens, or even purples depending on the minerals that replaced the original organic material.
Why is Coprolite Important?
- Offers rare and direct insight into prehistoric diets
- Helps scientists determine if the dinosaur was a carnivore or herbivore
- May contain bone fragments, plant matter, or shell, visible under magnification
- Adds unique variety to any fossil or natural history collection
- Fascinating educational specimen for schools, museums, or curious collectors
