Western Morning News500-million-year-old fossil helps fill a strange gap in our record of life on Earth
Artist's reconstruction of _Magnicornaspis garwoodi_ in life. Thomas TurnerRoughly 500 million years ago, a strange event in the evolution of life on Earth seems to have taken place. The known fossil record from this time, which falls within the Cambrian period, contains a missing chapter. Palaeontologists refer to it as the “Furongian gap”. And it’s striking because there is an explosion of biodiversity within the fossil record both immediately…
490-Million-Year-Old Arthropod Fossil Reveals Critical Insights into Evolutionary Gaps in the Fossil Record
A newly discovered species of Corcoranidae arthropod, identified as Magnicornaspis garwoodi, lived during the Furonian period, approximately 497 to 487 million years ago. This well-preserved specimen was unearthed near Quebec, Canada, and provides significant evidence that the Frondian gap—the evolutionary interval between the Cambrian explosion and the Ordovician Great Biodiversity Event—may reflect sampling bias rather [...] The post 490-Milli…
A new species of arthropod, named Magnicornaspis garwoodi, has been identified from an exceptionally well-preserved fossil found near Quebec City, Canada. The discovery, dating back to the Furongian period, between 497 and 487 million years ago, contributes to the understanding of biodiversity during that time. Identification of the new arthropod species: Magnicornaspis garwoodi belongs to the corcoraniidae group and exhibits characteristics suc…
