Quantitative reconstruction of body size evolution among non-hadrosauriform ornithopods.

<p>Black circles represent body size (based upon femoral length) of terminal taxa, whereas grey circles indicate reconstructed ancestral body sizes. Within the clade Rhabdodontidae two values for femoral length are reconstructed at each ancestral node: values in bold were calculated using the topology shown here, whereas non-bold values were reconstructed using a topology in which <i>Rhabdodon</i> was split into giant and small species.
