FIGURE 9 in Taxonomic assessment of Alligator Snapping Turtles (Chelydridae: Macrochelys), with the description of two new species from the southeastern United States
FIGURE 9. Bayesian inference phylogeny for extant chelydrids (Chelydra and Macrochelys). Note that representative skeletal synapomorphies in skull and carapace (above and below, respectively, next to lineage name) are provided for each lineage of Macrochelys; values above major nodes represent posterior probabilities (≥ 95%); values below major nodes represent the mean divergence time estimation of the most recent common ancestor (MRCA); and bars at major nodes represent 95% Highest Posterior Density (HPD).

American alligator ultrasound and microCT
<p class="MsoNormal">Unlike the majority of sauropsids, which breathe primarily through costal and abdominal muscle contractions, extant crocodilians have evolved the hepatic piston pump, a unique ventilatory mechanism powered by the diaphragmaticus muscle. This muscle attaches to the pelvis and the liver, pulling the liver and viscera caudally during inspiration and lowering pressure in the pleuroperitoneal cavity, helping to inflate the lungs. It has been hypothesized that the hepatic piston pump is coupled to modifications in the axial skeleton that result in a smooth interior thoracic ceiling, facilitating craniocaudal translation of the viscera during ventilation. We assess this using ultrasound video to visualize the hepatic-piston apparatus in breathing sub-adult and adult individuals (n = 7) of the American alligator (<em>Alligator mississippiensis</em>). The magnitude of displacement of the liver was calculated by measuring the distance between the most cranial and most caudal positions of the liver during a breath cycle. These data demonstrate that pleural tissues are freely sliding cranially and caudally along the thoracic ceiling. Based on our results, we suggest that features associated with the presence or absence of a smooth thoracolumbar ceiling are viable osteological correlates for reconstructing the evolution of the hepatic piston pump in extinct crocodyliform archosaurs.</p>

FIG. 5 in Nest Attendance Patterns in the American Alligator (Alligator mississippiensis)
FIG. 5. Nest visits were temperature-dependent, as most of the visits occurred at night when temperatures were lower, or, observationally, during periods of cloudy weather with thunderstorms during the mid-morning hours of the 2012 season.
FIG. 4 in Nest Attendance Patterns in the American Alligator (Alligator mississippiensis)
FIG. 4. An alligator confronts a wild hog in a nest defense behavior. The eggs were deposited in the nest on 10 June 2011, and thus this photo was captured on the second day after egg deposition. This was the only photo captured in the sequence. There was no damage to the nest, and no hair or blood was found at the nest site; thus, we assume that this confrontation resulted in a successful nest defense for the alligator.
FIG. 3. Cumulative rainfall for coastal southeast Texas. Note that the 2011 field season experienced only 54.8 in Nest Attendance Patterns in the American Alligator (Alligator mississippiensis)
FIG. 3. Cumulative rainfall for coastal southeast Texas. Note that the 2011 field season experienced only 54.8% of the normal rainfall through the first nine months of the year, while the 2012 season has much higher rainfall (71% above normal). This time frame covers the entire breeding, nesting, and incubation periods for alligators, and nest attendance patterns were not different between years despite drastic difference in climatic conditions.
