Ryosuke Motani. Department of Earth and Planetary Sciences, University of California Davis, Davis, California, USA. rmotani@ucdavis.edu
Professor at the University of California at Davis. Major research focus is on the use of physics-based functional morphology to probe physical constraints behind the evolution of animal shapes. Questions along this line include: what made tunas, lamnid sharks, cetaceans, and ichthyosaurs all look similar in silhouette; what constraints were behind the long necks of elasmosaurs (long-necked plesiosaurs)? Complementary research topics cover phylogenetics, systematics, and their integration with physical functional morphology. Taxonomic strength is in Mesozoic marine reptiles, especially ichthyosaurs (Ichthyopterygia), and field experiences mostly in Mesozoic marine deposits.

David Ward qualified as a veterinarian at the Royal Veterinary College, London, UK in 1974, but after working for some years as a small animal clinician migrated into vertebrate palaeontology. His main interest was in microvertebrates, more particularly their extraction from sediment with the least effort and damage, This provided him with a number of outstanding shark and ray assemblages that with the assistance of Charlie Underwood and his students, made it into print. Now in his mid-70's he still loves fieldwork but is less keen on camping. David's current interests include Mesozoic and Cenozoic Lamniform sharks, rays and chimaeroids, coprolites, public outreach and Late Cretaceous coprolites.
