Name: Arcestes

Specimen: Ammonite

Age: Triassic

Location: Indonesia

Size (picture scale cube=1cm): 25 x 23 x 14mm (0.98 x 0.91 x 0.55 inches)

 

Ammonites are one of the most recognisable fossils around, this is due to their familiar spiral shape shell, reminiscent of what we know as a snail shell, though these creatures are not related to snails at all. They were marine animals, present between 240 – 65 million years ago, who had a coiled external shell like that of the modern nautilus, and although they resembled a modern-day nautilus, these molluscs are more closely related to living coleoids i.e. octopuses, squid, and cuttlefish!

These creatures varied in size, ranging from only a few millimetres to some fossils being found measuring a whopping 8 feet 96 inches.

 

ACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.

Triassic Information

The Triassic Period (252–201 million years ago) marked the beginning of the Mesozoic Era, following the Permian-Triassic mass extinction, the most severe extinction event in Earth's history. The climate was hot and dry, with vast deserts and little polar ice. Life slowly recovered, leading to the rise of the first dinosaurs, pterosaurs (flying reptiles), and early mammals. Reptiles, including large archosaurs (ancestors of crocodiles and dinosaurs), dominated both land and sea. In the oceans, ichthyosaurs and plesiosaurs thrived alongside ammonites and early coral reefs. The first true conifers and ginkgo trees spread across the land. The period ended with another mass extinction, paving the way for the Jurassic and the golden age of dinosaurs.
