3283: 3469:). This specimen shows signs of regrowth of bone around the injury as well as subsequent infections that were ongoing at the time of the mosasaur's death, which may have been partially caused by the injuries inflicted. The specimen stands as one of the few clearly confirmable cases of intra-specific combat between mosasaurs. It also revealed a very atypical immune response to the infection. Unlike modern reptilians where solid fibrous masses are produced to contain infections, this mosasaur showed a much more mammal-like response, including liquid pus. This is one of the first cases in which immunological responses in fossil taxa have been studied in such detail and where extant relatives differ to extinct taxa. 3066: 3099: 918: 3077: 1220: 3087: 1476: 155: 1321: 126: 3404: 1059: 2826: 5126: 5584: 2475: 707: 1370: 880: 1703: 1290:, where knowledge of the teeth mainly comes from isolated specimens. Known teeth are strongly bicarinate with a weak serration on both carinae. The carinae then divide the teeth into lingual and labial surfaces, with the lingual surface being more convex and large in comparison with the labial. The teeth have a slight posterior and medial recurvature and are noted for having smooth surfaces (which is different from other species of 2339: 3326:. For instance, the anterior teeth are more incurved and slender than those posterior to them with a gradual change in shape along the tooth row. The anterior teeth have a ratio of crown length to basal crown width of 2.0 to 2.5, whereas teeth in the middle of the tooth row have ratios in the range of 1.7 to 2.0. These ratios are consistent with both mosasaurs with "cutting" and "crushing" teeth. Though robust, the teeth of 3251:. As with most mosasaurs, the teeth of these specimens are carinate, with the carinae aligned roughly parallel to the jaw. On unworn teeth, the apex is acute but blunt, and has fine, wavy, anastomosing ridges for as much as 25% of the crown height. Such ornamentation could potentially strengthen the teeth. The blunt tip and roughened surface suggest a tooth that was used for capturing fairly hard prey, and the presence of 2354: 1348:

It is clear that the wear on the teeth does not represent simple breakage, since that would result in different amounts of wear on different teeth. In contrast to the marginal teeth, the pterygoid teeth, though unusually large for a mosasaur, do not exhibit any wear. This suggests that the marginal
