Swedish hesperornithiforms - new paper
Rees, J. and Lindgren, J. (2005). Aquatic birds from the Upper Cretaceous
(Lower Campanian) of Sweden and the biology and distribution of
Hesperornithiforms. Palaeontology 48(6): 1321-1329.
ABSTRACT. "Isolated skeletal elements of three hesperornithiform taxa are
recorded from marine strata of latest early Campanian (sensu germanico) age
in the Kristianstad Basin, southern Sweden. The material comprises
_Hesperornis rossicus_ Nessov and Yarkov, one of the largest Mesozoic
aquatic birds known to date, _Hesperornis_ sp. and _Baptornis_ sp. The
holotype (a dorsal vertebra) of _Parascaniornis stensioei_ Lambrecht is
re-examined, and the nominal species is here considered as a nomen dubium
because no diagnostic features can be found that separate the type from
dorsals of _Baptornis advenus_. The distribution and palaeobiology of
hesperornithiforms are reviewed."
