English ammonites are highly prized fossils known for their intricate designs and exceptional preservation, offering a window into the prehistoric seas that once covered much of England. These ancient marine mollusks, which lived millions of years ago during the Mesozoic Era, are found in a variety of regions across England, including the famous Jurassic Coast in Dorset. English ammonites often feature well-defined spiral shapes and can range from small, affordable specimens to large, impressive pieces with detailed patterns. Their fossils provide valuable insights into the biodiversity of ancient marine life and are cherished by collectors, paleontologists, and fossil enthusiasts.

Ammonites from England are available at various price points, with small, budget-friendly fossils starting at just a few dollars, while larger, higher-quality specimens can be more expensive. Known for their authenticity and geological significance, English ammonites make excellent additions to fossil collections worldwide. With a rich history and an abundance of stunning specimens, English ammonites are a fantastic way to learn about Earth’s ancient oceans while adding a genuine piece of prehistoric history to your collection.

Ammonites from England

1. What is an ammonite?
Ammonites are extinct marine mollusks that lived during the Mesozoic Era, characterized by their spiral, coiled shells. They are related to modern cephalopods, like squids and octopuses, but unlike their living relatives, ammonites had hard, protective shells. English ammonites are especially notable for their fossil diversity and are often highly prized by paleontologists and fossil collectors. These ammonites, preserved in rock formations throughout England, offer insights into the ancient marine ecosystems and contribute significantly to our understanding of Earth’s geological history.

2. How old are English ammonites?
English ammonites primarily date back to the Jurassic and Cretaceous periods, which spanned from approximately 201 to 66 million years ago. England’s fossil-rich regions, such as Dorset and the Yorkshire coast, contain ammonite fossils from these periods. The Jurassic period, in particular, saw the highest diversity of ammonites in England. Fossils from this era are often found in limestone and clay deposits, with some of the oldest and best-preserved ammonite fossils found in the famous “Jurassic Coast” of southern England, which is a UNESCO World Heritage site. These ammonites lived from about 200 to 66 million years ago before going extinct at the end of the Cretaceous period.

3. Where are ammonites found in England?
Ammonite fossils are found in several regions across England, with some of the most famous sites being located along the Jurassic Coast of Dorset and Devon, as well as in Yorkshire. The Jurassic Coast is renowned for its rich deposits of ammonites and other prehistoric creatures, often found in the cliffs and coastal rocks. In Yorkshire, particularly around the Whitby area, ammonites have been discovered in limestone formations, which provide a clear record of ammonite evolution. Other notable areas include the Isle of Wight and the Midlands, where ammonite fossils can be found in the local sedimentary rock layers.

4. How many species of ammonites are there in England?
England is home to hundreds of species of ammonites, with over 1,000 species identified across various regions. The ammonites found here vary greatly in size, shape, and shell ornamentation, and include genera such as Dactylioceras, Acanthoceras, Ammonites, and Perisphinctes. These ammonites are important for dating geological layers and studying the evolution of marine life. The diversity of ammonite species in England makes it a critical area for paleontological research, providing essential information about the prehistoric seas and the biodiversity that thrived during the Mesozoic Era.

5. How big did ammonites get in England?
Ammonites found in England could grow to considerable sizes, with some species reaching diameters of over 1 meter (3.3 feet). Among the largest ammonites discovered in England are species from the genus Turrilites, which were known for their large, tightly coiled shells. While many ammonites found in England are smaller, typically ranging from several centimeters to about 30 cm (1 foot), the larger specimens are highly prized by collectors. The larger ammonites from England often exhibit detailed and ornate shell structures, making them some of the most spectacular finds in fossil hunting.
