2.3" Wide Kosmoceras Ammonite in Matrix- England
This is a 2.3" wide Kosmoceras (Guliemiceras) jasoni ammonite from Ashton Keynes, Gloucestershire, England. The ammonite is beautifully prepared in the matrix in which it was found. They are often found in clusters which can lead to parts of other ammonites or gastropods to become part of the matrix. This makes each specimen unique and truly one of a kind.
About Ammonites
Ammonites were ancient marine cephalopods, similar to today's squids and octopuses, but with a defining feature: their distinctive, tightly coiled spiral shells. These shells, resembling those of modern nautiluses, served as both a protective home and a buoyancy aid, allowing ammonites to navigate the prehistoric seas with ease. First emerging around 240 million years ago in the Triassic Period, ammonites thrived for over 175 million years, adapting through numerous forms and sizes. As predatory creatures, they likely fed on smaller marine organisms, using their tentacles to capture prey. However, their long reign came to an end 65 million years ago at the close of the Cretaceous, coinciding with the mass extinction event that also eliminated the dinosaurs.
