Description

The beautiful ammonite you see here nestled amongst the seaweed and modern oysters clinging to the grey shales of the Northumberland Formation is the late Cretaceous ammonite Pachydiscus suchiaensis. This is one of my favourite species and is treasured both for its beauty and the fossil site it hails from. This darling was found in situ in the 72 million-year-old sediments at Collishaw Point on the northwest side of Hornby Island, southwestern British Columbia, Canada.
