Their teeth were flat and ate mollusks and shellfish. Approximately 86% of the total variance in the dataset is explained by principal components (PC)1-PC3 (Figures 1C, S2A, and S2B).PC1 (64.8% of the total variance) describes a range from apicobasally tall and mesiodistally narrow to short and wide tooth morphologies (Figure 1C).PC2 (11.43%) captures distally recurved teeth with reduced cusplets to upright and mesially . The shark fauna of the Upper Cretaceous Hinoshima Formation (Santonian: 86.3-83.6 Ma) of the Himenoura Group (Kamiamakusa, Kumamoto Prefecture, Kyushu, Japan) was investigated based on fossil shark teeth found at five localities: Himedo Park, Kugushima, Wadanohana, Higashiura, and Kotorigoe. Majungasaurus was a medium-sized . In addition, the squamation pattern and some morphofunctional interpretations of cretoxyrhinids also support an adaptation to fast swimming, more congruent with values estimated for the scenario of . These are family units that may include up to three males, a dozen or so females, and their young. This here's a quick look at Jurassic Kratts, a prehistoric park parody, enjoy the preview.
