Figure 2 in Body size estimation and evolution in metriorhynchid crocodylomorphs: implications for species diversification and niche partitioning
Figure 2. Evolutionary relationships of metriorhynchid genera based on the new phylogenetic analysis presented herein. Geological ranges are based on the taxonomic compendium in Young et al. (2010). Labelled nodes represent clades: (1) Metriorhynchidae; (2) Metriorhynchinae; (3) Geosaurinae; and (4) Geosaurini.
Figure 5 in Body size estimation and evolution in metriorhynchid crocodylomorphs: implications for species diversification and niche partitioning
Figure 5. Ordination plot of femoral length against total body length in living and fossil crocodylomorphs. The taxa from Farlow et al. (2005) are in light grey, and their Alligator 95% prediction interval is shown by the two parallel oblique lines.

Data from: Largest-known fossil penguin provides insight into the early evolution of sphenisciform body size and flipper anatomy
<p>Recent fossil discoveries from New Zealand have revealed a remarkably diverse assemblage of Paleocene stem group penguins. Here, we add to this growing record by describing nine new penguin specimens from the late Paleocene (upper Teurian local stage; 55.5–59.5Ma) Moeraki Formation of the South Island, New Zealand. The largest specimen is assigned to a new species, <em>Kumimanu fordycei</em> sp. nov., that may have been the largest penguin ever to have lived. Allometric regressions based on humerus length and humerus head width of extant penguins yield mean estimates of a live body mass in the range of 159.4 kg (95% CI: 143.4 kg–179.6kg) and 148.7 kg (95% CI: 143.4kg–180.0kg), respectively, for <em>Kumimanu fordycei</em>. A second new species, <em>Petradyptes stonehousei</em> gen. et sp. nov., is represented by five specimens and was slightly larger than the extant emperor penguin <em>Aptenodytes forsteri</em>. Two small humeri represent an additional smaller unnamed penguin species. Parsimony and Bayesian phylogenetic analyses recover <em>Kumimanu</em> and <em>Petradyptes</em> crownward of the early Paleocene mainland NZ taxa <em>Waimanu</em> and <em>Muriwaimanu</em>, but stemward of the Chatham Island taxon <em>Kupoupou</em>. These analyses differ, however, in the placement of these two taxa relative to <em>Sequiwaimanu</em>, <em>Crossvallia</em>, and <em>Kaiika</em>. The massive size and placement of <em>Kumimanu fordycei</em> close to the root of the penguin tree provide additional support for a scenario in which penguins reached the upper limit of sphenisciform body size very early in their evolutionary history, while still retaining numerous plesiomorphic features of the flipper.</p>
