RARE Jeletzkytes Ammonite Fossil Pierre Shale Late Cretaceous North Dakota USA

Description

RARE Jeletzkytes Ammonite Fossil

## A genuine Late Cretaceous ammonite from North Dakota

This rare Jeletzkytes ammonite is a genuine fossil specimen recovered from the Pierre Shale of North Dakota, USA. Dating to the Late Cretaceous, spanning the Campanian–Maastrichtian interval, it represents a fascinating chapter in the history of the Western Interior Seaway, the vast inland sea that once covered much of central North America. The photographs show the exact carefully chosen fossil you will receive, making this a distinctive addition for fossil collectors, ammonite enthusiasts, geology students and natural-history display collections.

## Fossil type and scientific interest

Ammonites were extinct marine cephalopods related to modern nautiluses, squid and octopuses. Their characteristic chambered shells supported buoyancy and their often intricate sutures make them enduringly popular with collectors. Jeletzkytes is a recognised ammonite genus from the latest portion of the Cretaceous record in North America. Its occurrence within the Pierre Shale places this specimen in a celebrated marine sedimentary succession known for preserving ammonites and other evidence of ancient sea life.

The Pierre Shale was deposited as fine sediment settled through quiet offshore waters of the Western Interior Seaway. Over geological time, that sediment compacted and lithified, preserving marine fossils within shale beds. This specimen is therefore not simply an attractive natural object: it is tangible evidence of an ancient marine ecosystem that existed shortly before the end of the Age of Dinosaurs.

## Locality, age and provenance

– Species / fossil type: Jeletzkytes ammonite

– Formation: Pierre Shale

– Geological age: Late Cretaceous, Campanian–Maastrichtian

– Locality: North Dakota, USA

– Environment: Marine sediments of the Western Interior Seaway

The Campanian–Maastrichtian stages are particularly important to collectors because they record the final millions of years of the Cretaceous Period. A North Dakota Pierre Shale ammonite offers a direct connection to this late Mesozoic marine world and makes a thoughtful geology gift for anyone interested in palaeontology, ammonite fossils or American fossil localities.
