The Gavialis–Tomistoma debate: the contribution of skull ontogenetic allometry and growth trajectories to the study of crocodylian relationships
SUMMARY The phylogenetic placement of Tomistoma and Gavialis crocodiles depends largely upon whether molecular or morphological data are utilized. Molecular analyses consider them as sister taxa,Expand

  • 1 August 2006
Abstract The island rule is the phenomenon of the miniaturization of large animals and the gigantism of small animals on islands, with mammals providing the classic case studies. Several explanationsExpand

The shape of the mandibular corpus in large fissiped carnivores: allometry, function and phylogeny
Mandibular corpus shape variability was investigated in seven families of both extant and extinct mammalian carnivores using two-dimensional landmarks and geometric morphometric methods. The landmarkExpand

One size does not fit all: no evidence for an optimal body size on islands
Aim  Optimal body size theories predict that large clades have a single, optimal, body size that serves as an evolutionary attractor, with the full body size spectrum of a clade resulting fromExpand

Turnover pulse or Red Queen? Evidence from the large mammal communities during the Plio-Pleistocene of Italy
Abstract This study investigates the effect of climate changes (during the Ice Ages) on the evolution of Plio-Pleistocene large land mammal communities of the Italian peninsula. We recognizedExpand

Ecological Specialization in Fossil Mammals Explains Cope’s Rule
Cope’s rule is the trend toward increasing body size in a lineage over geological time. The rule has been explained either as passive diffusion away from a small initial body size or as an activeExpand

Slaying dragons: limited evidence for unusual body size evolution on islands
Aim Island taxa often attain forms outside the range achieved by mainland relatives. Body size evolution of vertebrates on islands has therefore received much attention, with two seeminglyExpand

Bite of the cats: relationships between functional integration and mechanical performance as revealed by mandible geometry.
Cat-like carnivorous mammals represent a relatively homogeneous group of species whose morphology appears constrained by exclusive adaptations for meat eating. We present the most comprehensive dataExpand

The blue lizard spandrel and the island syndrome
BackgroundMany small vertebrates on islands grow larger, mature later, lay smaller clutches/litters, and are less sexually dimorphic and aggressive than their mainland relatives. This set ofExpand

The fast life of a dwarfed giant
In the first half of the 1960s, a rich paleontological site was discovered at Spinagallo caves (Eastern Sicily, Southern Italy). A very abundant fossil population (at least 104 specimens) of theExpand
