 Calymene Fossil in Spain

    Calymene(2)

   Summary Author:  Carlos Gómez Fernández

   Hidden within the landscape around the  Cijara Lake and reservoir in
   western Spain are metamorphic shakes dating to the  Ordovician
   Period. During this geologic period that occurred between 485 and 444
   million years ago, global ocean levels were exceptionally high, which
   led to considerable  sediment deposition on the seabed. As a result
   of combined processes of high temperatures and pressures, specimens
   buried in these sediment layers were preserved as  fossils. One such
   outstanding example is the  calymene fossil shown in the photo
   above. Despite the harsh environmental conditions over the past several
   hundred million years, the very fragile fossil remains almost fully
   intact. The 50mm diameter camera lens serves as a scale for this
   specimen. This photo was taken on February 3, 2022.
