£ 60.00
Canadoceras yokoyamai Ammonite Fossil from British Columbia, CanadaThis is a genuine Canadoceras yokoyamai ammonite fossil from the Haslam
Formation, dating to the Upper Cretaceous, Cenomanian stage, collected from Brannan Lake, British Columbia, Canada. This carefully chosen fossil is a desirable North American Cretaceous marine cephalopod specimen, selected for its natural form, geological interest, and collectable display appeal. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it a trusted addition to an ammonite collection, fossil cabinet, natural history display, educational geology collection, or prehistoric gift selection.The photograph shows the actual fossil specimen you will receive. Full sizing and scale can be seen in the photo.Geological Age and FormationThis ammonite comes from the Haslam Formation, a fossil-bearing marine sedimentary unit of British Columbia. It dates to the Cenomanian stage of the Upper Cretaceous, approximately 100 to 94 million years old. The Cenomanian was a time of warm global climates, high sea levels, and extensive marine environments around many continental margins.The Haslam Formation is associated with Cretaceous marine deposition along the western margin of North America. Sediments such as mudstone, siltstone, sandstone, and marine shale accumulated in ancient sea-floor environments, preserving ammonites and other marine fossils. Fossils from this formation are valued because they represent the diverse marine life of the Pacific margin during the age of dinosaurs.Location: Brannan Lake, British ColumbiaThis specimen was collected from Brannan Lake in British Columbia, Canada, a locality linked to the fossil-rich Cretaceous geology of Vancouver Island and the surrounding region. During the Cenomanian, this area was part of an ancient marine setting influenced by offshore waters, sediment input, and active basin development along the western edge of North America.The rocks in this region record a marine world very different from the modern landscape of British Columbia. Instead of the present coastline, forests, and lakes, the area was once associated with Cretaceous seaways where ammonites, bivalves, gastropods, crustaceans, fish, and other marine organisms lived and were preserved in sediment.Fossil Type and SpeciesThis fossil is identified as Canadoceras yokoyamai, an extinct ammonite species. Ammonites were marine molluscs related to modern squid, cuttlefish, octopus, and nautilus. They had hard external shells divided internally into chambers. The living animal occupied the outer body chamber, while earlier chambers helped regulate buoyancy, allowing the ammonite to move through the water column.Canadoceras is a Cretaceous ammonite genus associated with the family Pachydiscidae, a group of generally robust ammonites known from Late Cretaceous marine deposits. These ammonites are valued by collectors for their strong shell form, scientific significance, and connection to the marine ecosystems that existed while dinosaurs still lived on land.Morphology and Notable FeaturesCanadoceras ammonites are appreciated for their bold Cretaceous appearance and classic coiled shell form. Depending on preservation, specimens may show visible whorls, a defined umbilical area, ribbing or growth lines, shell texture, mineralisation, and natural surface detail. The shell grew in a spiral through the animal’s life, with each new whorl representing a later stage of development.The internal shell was divided into chambers by walls called septa. Where these septa met the outer shell, they formed suture lines, which are important in ammonite classification. Even where fine sutures are not fully visible, the whorl shape, shell proportions, ornamentation, and overall structure preserve valuable evidence of the ammonite’s biology and Cretaceous marine environment.As a genuine fossil, this specimen may show natural matrix, fossil shell texture, mineral staining, colour variation, weathering, small chips, cracks, or areas of natural wear caused by fossilisation and geological history. These natural features are normal for authentic fossils and add to the individuality of the piece. The photo shows the exact fossil being offered, allowing the buyer to view its preservation, condition, size, and display quality before purchase.Cretaceous Marine EnvironmentThis Canadoceras yokoyamai ammonite lived in the marine waters of what is now British Columbia during the Cenomanian. These seas supported a varied ecosystem of swimming cephalopods, fish, and seabed-dwelling invertebrates. Ammonites were active swimming or drifting animals, likely feeding on small prey in the water column using tentacles.After death, the ammonite shell could settle onto the sea floor and become buried by sediment. Over millions of years, mineralisation, compaction, and geological change transformed the shell and surrounding sediment into fossil-bearing rock. This specimen is a direct link to the ancient Cretaceous seas of western Canada, when dinosaurs lived on land and ammonites flourished in the oceans.Authenticity and CollectabilityThis Canadoceras yokoyamai ammonite fossil is a genuine specimen from Brannan Lake, British Columbia, Canada, dating to the Cenomanian stage of the Upper Cretaceous within the Haslam Formation. It is suitable for collectors of Canadian fossils, Cretaceous ammonites, North American fossils, marine cephalopods, natural history specimens, educational geology pieces, and display fossils.This carefully selected fossil includes a Certificate of Authenticity lifetime guarantee generic card, and the fossil shown in the photo is the actual specimen you will receive.
