New information on the Late Jurassic ichthyosaur Nannopterygius

Recommended Posts

A new ichthyosaur-related paper is available online:


Nikolay G Zverkov and Megan L Jacobs. 2020. Revision of Nannopterygius (Ichthyosauria: Ophthalmosauridae): reappraisal of the ‘Inaccessible’ holotype resolves a taxonomic tangle and reveals an obscure ophthalmosaurid lineage with a wide distribution. Zoological Journal of the Linnean Society zlaa028. DOI: 10.1093/zoolinnean/zlaa028


The description of Nannopterygius borealis from the Arctic circle and the synonymization of the Kimmeridgian-Tithonian genera Paraophthalmosaurus and Yasykovia with Nannopterygius offers new insights into the genus Nannopterygius, as the holotype of N. enthekiodon was mounted in a location that made it inaccessible in some respects, and Paraophthalmosaurus and Yasykovia were until recently considered probable synonyms of Ophthalmosaurus. Like Arthropterygius, Nannopterygius was widespread in waters at high latitudes.


By the way, could anyone send me a copy of the above-mentioned paper?
