This listing offers a rare and substantial fossil section of a giant turtle shell, dating to the Cretaceous Period, and originating from Australia. This is a large carapace (shell) fragment, representing a prehistoric marine or freshwater turtle that lived during the age of the dinosaurs.

Fossil Type:

Specimen: Turtle Shell Fossil (Carapace Section)

Likely from a large cryptodiran turtle based on structural and regional indicators

Geological Context:

Period: Cretaceous

Estimated Age: ~100–66 million years ago (exact stage unspecified due to locality constraints)

Depositional Environment: Likely fluvial or marginal marine settings; turtles during this time inhabited both freshwater rivers and coastal marine lagoons

Turtle Coprolite Fossil - Eocene - Madagascar - Genuine Prehistoric Specimen + COA

For sale is an authentic Turtle Coprolite fossil from the Eocene Epoch, discovered in Madagascar. This well-preserved specimen represents the fossilized excrement of an ancient turtle, offering a fascinating glimpse into the diet and ecosystem of prehistoric reptiles that lived approximately 56 to 33.9 million years ago.

Geology & Fossil Type:

Coprolites are trace fossils, meaning they preserve evidence of ancient life rather than the organism itself. This Turtle Coprolite was formed when prehistoric turtles excreted waste that became mineralized over millions of years, preserving its shape and internal composition. These fossils are scientifically significant as they provide insights into the feeding habits and digestive systems of ancient reptiles.

The Eocene Epoch was a time of significant evolution for many reptilian species, and Madagascar was home to a diverse array of wildlife, including ancient turtles. This fossil provides a direct connection to these prehistoric ecosystems, making it a valuable and rare paleontological specimen.

Fossil Shark Coprolite with Fish Scales & Bone London Clay Eocene Isle of Sheppey Kent UK Authentic Specimen

This listing features a fossilised shark coprolite (poo) containing preserved fish scales and bone fragments, collected from the world-renowned London Clay Formation on the Isle of Sheppey, Kent, UK. This is a carefully selected and scientifically significant specimen from the Lower Eocene Epoch, and comes with a Certificate of Authenticity.

Coprolites are trace fossils representing the preserved faeces of ancient animals. In this case, the specimen is attributed to a predatory shark, as indicated by the inclusion of fish scale and bone material—evidence of diet and digestive processes in Eocene marine ecosystems.

The London Clay Formation is one of the most fossiliferous geological units in Europe, formed approximately 56 to 47.8 million years ago during the Ypresian Stage of the Eocene Period. The environment was a shallow, subtropical marine shelf rich in diverse marine fauna, including sharks, rays, bony fish, turtles, and crocodilians.

Morphology Features:

Irregular to spiral or elongate form typical of vertebrate coprolites

Mineralised matrix with embedded fish scale and bone inclusions

Brown-grey coloration due to clay mineral preservation

Often contains phosphatic components from digestive processes

These inclusions make this coprolite especially valuable as a direct window into predator-prey interactions and dietary evidence of ancient marine vertebrates.

Rare Fossil Crocodile Tooth DIPLOCYNODON Bracklesham Beds Eocene Lee-on-Solent Hampshire UK Authentic Specimen

This listing features a rare fossilised crocodile tooth from the extinct genus Diplocynodon, collected from the Bracklesham Beds Formation at Lee-on-Solent, Hampshire, UK. This is a carefully selected specimen from the Eocene Epoch and includes a Certificate of Authenticity.

Diplocynodon was a basal alligatoroid crocodilian, known from freshwater and coastal habitats in Europe during the Paleogene. The genus thrived during the Eocene, particularly the Lutetian Stage (~47.8 to 41.3 million years ago), and is notable for being one of the few crocodilians adapted to cooler climates.

The Bracklesham Beds, part of the Bracklesham Group, are a series of marine and marginal-marine sediments deposited in a subtropical estuarine to shallow marine environment. These sediments are well-known for their diverse assemblage of fossil vertebrates, including sharks, rays, fish, turtles, and reptiles like Diplocynodon.

Morphology Features:

Conical, robust shape typical of generalist feeding crocodylians

Smooth enamel surface with slight basal ridges in some specimens

Root often preserved, showing natural wear from fossilisation

Dark brown to black coloration from mineralisation in marine clay

This genuine crocodile tooth is an excellent representation of Eocene reptilian fauna and makes an ideal addition to both private collections and educational displays.
