Named By: Tai Kubo, Mark T. Mitchell & Donald M. Henderson - 2012.
Classification: Chordata, Reptilia, Sauropterygia, Plesiosauria, Elasmosauridae.
Species: A. vanderveldei (type).
Size: About 11.5 - 12 meters long.
Known locations: Canada, Alberta - Bearpaw Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Almost complete post cranial skeleton.
is one of the best preserved elasmosaurid
plesiosaurs to be discovered
in Canada, and has a total of 76 cervical (neck) vertebrae
. Elasmosaurid pesiosaurs like Albertonectes are
noted for having
their long necks that are proportionately much longer than earlier
plesiosaur types. This would have been a specialist feeding
adaptation allowing for a longer reach when feeding upon fish.
The holotype specimen of Albertonectes shows signs of being scavenged, as evidenced by a tooth marked coracoid as well as two shed teeth believed to have come from the Sqaulicorax shark genus.
