Crepidula Fossil Bivalve Lower Miocene Clallam Formation Washington USA | Genuine Specimen

Original price was: £8.40.Current price is: £6.72.

A genuine and well-preserved Crepidula fossil bivalve from the Lower Miocene epoch, approximately 16–20 million years old. This fossil was discovered in the Clallam Formation of Northwestern Washington, USA, an important geological unit known for preserving a diverse assemblage of marine molluscs.

The genus Crepidula, commonly known as slipper shells, is a marine gastropod mollusc (often mistaken for a bivalve due to its shell shape) with a distinctive internal shelf structure. This specimen reflects the shallow marine environments of the early Miocene in the Pacific Northwest.

Fossil Type: Gastropod (commonly called a slipper shell, not a true bivalve)

Genus: Crepidula

Geological Age: Lower Miocene (approx. 16–20 million years ago)

Formation: Clallam Formation

Depositional Environment: The Clallam Formation was deposited in a shallow, warm marine setting with good water circulation, supporting abundant marine life. The sediments include sandstone and siltstone beds that preserved mollusc shells in fine detail.

Morphological Features:

  • Convex outer shell with a smooth to slightly ridged surface
  • Internal “shelf” typical of Crepidula species visible in some specimens
  • Preservation may include original shell material or internal moulds

Notable:

  • Authentic specimen from the Clallam Formation, Washington State
  • A well-known genus with evolutionary and ecological interest
  • Ideal for fossil collectors, educators, and marine paleontology enthusiasts
  • Actual item shown – photo depicts the exact specimen you will receive

Authenticity: All of our fossils are 100% genuine natural specimens and come with a Certificate of Authenticity. The photo includes a 1cm scale cube for reference – please view the image for accurate sizing.

 

Add this genuine Crepidula fossil to your collection – a classic marine mollusc from the Lower Miocene seas of the Pacific Northwest, showcasing a beautifully preserved snapshot of ancient ocean life.

Description

Crepidula Fossil Bivalve

This genuine Crepidula fossil bivalve is identified as a lower Miocene specimen from the Clallam Formation in Northwestern Washington, USA. It is an appealing addition to fossil collections focused on marine paleontology, Miocene geology, Pacific Northwest fossils, or geographically documented specimens from North America.

Geological Identification

The specimen is associated with the lower Miocene portion of the Clallam Formation. The Clallam Formation is an important geological unit of Northwestern Washington, and its fossils provide an opportunity to explore the life and environments represented in the region’s Miocene rocks. This specimen is presented specifically under the identification Crepidula fossil bivalve, with the lower Miocene Clallam Formation designation supplied for its geological context.

Collector Display

With its named fossil identification and documented formation and region, this piece is suitable for a personal fossil collection, educational display, geology study area, or natural history cabinet. It can also be used as a distinctive gift for collectors interested in fossil bivalves, Miocene specimens, Clallam Formation material, and fossils from Washington State.

The geological information makes this specimen especially useful for collection labeling and display. A collector may wish to present it alongside other fossils from the Miocene or other specimens connected with the geology of the Pacific Northwest. The supplied identification and locality provide a clear foundation for organizing the piece within a regional or chronological fossil collection.
