New Cloudina Species Discovered In Spain
Palaeontologists have discovered a new fossil species called Cloudina carinata, a small fossil with a tubular appearance and one of the first animals that developed an external skeleton between 550 and 543 million years ago. The discovery is documented in Precambrian Research. The fossils were found in the archaeological site El Membrillar (Badajoz), one of the few sites in Europe where the remains of Cloudina can be found. "The specimens display exceptional preservation, they appear preserved in three dimensions, and show their original form and numerous details of the shells", lead author Iván Cortijo says. "Cloudina carinata is characterized by its elaborate ornamentation and complexity of the shells and tube that are formed when inserted." read more
