| Description |
English: Waptia fieldensis Walcott, 1912 - fossil arthropod from the Cambrian of Canada. (lateral view; USNM 114259, United States National Museum - National Museum of Natural History, Washington D.C., USA; public domain photograph provided by the Smithsonian Institution)
The Middle Cambrian-aged Burgess Shale is the most famous fossil deposit on Earth. It is located near the town of Field in Yoho National Park, southeastern British Columbia, western Canada. The deposit is famous for its spectacular soft-bodied preservation - the organisms have had their appendages & internal organs preserved. Many tens of thousands of fossils have been collected from the Burgess Shale Formation over the last century. Hundreds of species are known. Many claim that Charles Walcott discovered the Burgess Shale Lagerstätte (as soft-bodied fossil deposits are called by paleontologists) in 1909. However, it was actually discovered in 1886 or 1888 by Richard McConnell, based on anomalocarid appendage material from Mt. Stephen, in the Campsite Cliff Member of the Burgess Shale Formation. The main collecting localities have been two quarries (Walcott Quarry and Raymond Quarry) on the western side of the ridge connecting Mt. Field and Wapta Mountain a little north-northeast of Field. Numerous other smaller localities have been identified in the same area and for many, many kilometers to the south. Collecting at the Burgess Shale was most intense in 1910-1917 (Charles Walcott), 1925-1930 (Harvard’s Museum of Comparative Zoology), 1966-1967 (Geological Survey of Canada), and 1975-2000s (Royal Ontario Museum). Seen here is Waptia fieldensis, a bivalved arthropod with a relatively small carapace - it has preserved antennae, eyes, appendages, and gills. A black band representing the gut is present. Classification: Animalia, Arthropoda, Pseudocrustacea, Waptiida Stratigraphy: Walcott Quarry Member, Burgess Shale Formation, Ptychagnostus praecurrens Interval-zone, lower Marjuman Stage, middle Middle Cambrian. Locality: Walcott Quarry, western side of ridge between Mt. Field and Wapta Mountain, north-northeast of the town of Field, southeastern British Columbia, southwestern Canada |
