An article published in the “Journal of Systematic Palaeontology” describes a research that proposes a taxonomic revision among ichthyosaurs, marine reptiles that lived in the Triassic and Cretaceous periods. Dean Lomax, a paleontologist at the University of Manchester, and Professor Judy Massare of Brockport College studied fossils of the species Ichthyosaurus communis and Ichthyosaurus intermedius concluding that they are actually the same species.
