new paper about old dinosaur
A new dinosaur paper, recommended for all ankylosaur workers:
Pereda-Suberbiola, J. 1994. Polacanthus (Ornithischia, Ankylosauria), a
transatlantic armoured dinosaur from the Early Cretaceous of Europe and
North America. Palaeontographica Abteilung A 232: 133-159 + 5 plates.
For those who aren't up on this thryreophoran contraversy, there has been a
debate for a couple of decades whether or not Polacanthus Owen 1865 is the
same beast as Hylaeosaurus Mantell 1832. [Hylaeosaurus, by the way, is the
often-forgotten third of Owen's original three dinosaurs, the others being
Megalosaurus and Iguanodon.] Pereda-Suberbiola, like Kirkland and Blows,
believe that these are two different sorts of ankylosaurs; Coombs and
Maryanska do not. In a related topic, the first three have argued that the
North American Hoplitosaurus marshi is really a species of Polacanthus.
This papers features some great anatomical plates and a modern
reconstruction of Polacanthus foxi.
