...Canada, the Barcode of Life Database can determine patterns of COI gene variation within a given group of specimens. If the specimens in question differ by more than a few percent in their base pairs of DNA in this gene, it is likely that they have come from different populations.

The new species of protorosaur, however, provides additional clues and suggests that the long neck in these animals may have been part of a unique and very effective method for capturing prey in water.
