Sunday, October 13, 2013. Reconstructing the skull of Neophoca palatina: a fossil relative of the Australian sea lion from the Pleistocene of New Zealand. When Morgan Churchill visited Dunedin for his EAPSI fellowship in July and August, we secured a loan of the holotype skull of Neophoca palatina. Our first stab at putting humpty dumpty back together. The brown skull is a cast of the type specimen, with a modern. Phocarctos skull for comparison. The holotype braincase of. Neophoca palatina] back togethe...

Tuesday, November 26, 2013. Reflections on the 2013 Society of Vertebrate Paleontology Conference in Los Angeles, California. I’ve been back in New Zealand now for a week since my month-long trip to the US ended. The primary purpose of the trip was to present some of my dissertation research at the SVP conference (Society of Vertebrate Paleontology) in Los Angeles. This was my ninth (! Meeting, and my seventh time presenting research. Photo courtesy Rebecca Hunt-Foster. Synonymy, and Dracorex. The marine...

Sunday, May 11, 2014. The best known fossil pinniped, part 2: How many species (.and genera) are there of Allodesmus, anyway? Last week I summarized the history of research on Allodesmus. How many species of Allodesmus. And how many genera of desmatophocids are there? On one extreme, one could take the view that there are only two genera – Allodesmus. 8211; and that Atopotarus. Are all synonyms of Allodesmus. How many genera of desmatophocids are there? I won’t bother with Allodesmus. Insufficient crania...

From the middle Miocene of California, Pseudotaria muramotoi. From the late Miocene of Japan, and Imagotaria downsi. From the late Miocene of California and Oregon.

The unfortunate taxonomic history of Alachtherium. The first fossil walrus was described in the mid 19. Century by Du Bus (1867) and named Alachtherium cretsii.

Saturday, March 15, 2014. Science Fiction Double Feature: Two new papers on the same day – a strange new fossil porpoise, and vertebrate taphonomy of the Purisima Formation. Yesterday saw the publication of two new papers: the first of which is about a new genus and species of bizarre porpoise from the Pliocene of California, and the second is the published version of my master’s thesis. The genus name referring to the dramatically shorter rostrum, and is also an homage to the half-beak fish, Hemiramphus.
