• Geological Age: Jurassic period, Kellaways Bed formation, 165 to 160 million years ago.
• Location: Gloucestershire, Yorkshire, UK.
• Family: Bivalve
• Species: Gryphaea bilobata

Gryphaea bilobata fossil specimens exhibit a wider shape than earlier gryphaea species, these samples are of Jurassic age, found in the Kellaways bed formation in Yorkshire, making them over 160 million years old. They are suitable for educational use and for collectors, as they show evolutionary changes, as well as excellent morphological details such as growth lines on the surface of their bronze coloured shells. Measuring approximately 7 cm in size, these samples will come supplied in a card tray with a label.

• Geological Age: Pleistocene period, 2,588,000 to 11,700 years ago.
• Location: Red Crag, Walton on Naze, UK.
• Family: Bivalve
• Species: Glycymeris glycymeris

Glycymeris Glycymeris fossil bivalve specimens, these shells, although tarnished yellow still show growth lines, hinges and more, they were excavated from the Red Crag formation in Walton on Naze, UK and are excellent Pleistocene fossil samples for those with an interest in more recent fauna. Shells are approximately 4 to 5 cm in size and come supplied in a card tray with a label.
