Coprolites
The study of fossil coprolites has become a
discipline in itself, all be it one with only a few
specialists. The thought of fossil poop that is
millions of years old captivates both fossil
collectors and non-collectors alike, but the
study of coprolites can show the diet of extinct
animals in a manner almost no other fossils
can.

Fossil coprolites are known from the
Palaeozoic right through to the last ice age.
The earliest readily available coprolites are
from sharks and fish in the Devonian, but are
often only of a micro size. In the Mesozoic
with the dawn of the dinosaurs the first large
specimens begin to occur in abundance with
specimens the size of basketballs being
known.

The coprolites of herbivores can preserves
fragments of vegetation and seeds, even
those from the Mesozoic. Carnivore coprolites
are often rich is phosphate from digested
bones but can still contain fish scales and
bone fragments. Permian shark coprolites
even show that cannibalism took place at
times with adults eating juveniles of the same
species.

Right: A series of thin sections showing the
internal structures of coprolites. Top and
middle are Orthocanth shark coprolites from
the Lower Permian and show abundant fish
scales. The lowermost image is a reptilian
example from the Triassic of New Mexico and
shows some bone flecks.

shape. Similar to some tortoise coprolite we have seen at the zoo.
Madagascar Miocene Coprolite #6 - £50/$80
The biggest and best we have had. Enormous and a perfect display piece.
Measures 22 cm (nearly 9 inches long). Highly recommended
Jurassic - Lyme Regis, England
Hybodus shark coprolite (sml) - £6/$10
Hybodus shark coprolite (med) - £12/$15
Hybodus shark coprolite (lrg) - £12/$15
Ichthyosaur coprolite - £12/$15
The following specimens are all slices of coprolite from the famous Jurassic beds of Lyme Regis. The
spirals of the shark coprolites can be clear to see, as can fish scale inclusions.
Ichthyosaur scale rich coprolite - £25/$35
Cretaceous
Maiasaur small coprolite - £5/$8
These neat slices of coprolite came from
specimens found next to a Maiasaur nesting
ground in the Two Medicine Formation. Each
is housed in a 1.25 inch gem jar and comes
with an ID card as shown. Plant fragments
have been found in some of these specimens.
Triassic
Miocene
Bull Canyon Small Triassic Coprolites - £3/$5 each
Very good quality specimens from the New Mexico dinosaur beds.

Each comes housed in a gem jar with photo ID card as shown.
Permian
Lower Permian Shark Coprolites - £3/$5 each
Very good quality specimens from the Lower Permian of Waurika,
Oklahoma.

Each comes housed in a gem jar with photo ID card as shown.
Morrison Formation coprolite slice - £3/$5
These neat slices of coprolite come from the
famous dinosaur beds of the Morrison
Formation in Utah. Each has been agatised
and show the attractive colours typical of this
form. Comes with an ID card as shown.
Pliosaur Coprolite
£75/$125
This huge, rare
specimen is from the
Jurassic of England. It's
large size suggests it
can only be from the
largest of the marine
reptiles, most likely a
Pliosaur. It is heavily
phosphatised due to the
high bone content.
A rare piece and the
largest we have ever had.
Pleistocene
Florida Ice Age Alligator
Coprolite £6/$10
Nice, phosphate rich gator
coprolites from the Pleistocene.
Good, rare specimens.
Madagascar Miocene Coprolite
small - £3/$5 each
These are small examples from the same
beds as the larger specimens shown above.
Each has the same shape and are from
some of the smaller turtles.
Devonian
Rhynie Chert Arthropod
Coprolites - £15/$25 each

Preserved as masses of digested
spores, these tiny coprolites measure
1 to 2 mm across. They are slide
mounted thin sections are a
microscope is needed to properly
view them. Rare specimens
