Abstract Aside from large sharks such as Cretoxyrhina mantelli, there are no other marine species known from the Late Cretaceous which could challenge the role of mosasaurs as apex predators. From the evidence of the injuries observed on mosasaur remains, however, it is likely that they occasionally fought with or were attacked by other mosasaurs. Sometimes the injuries incurred in this combat were non-fatal and show evidence of healing prior to the death of the mosasaur, while in other… 

Cranial palaeopathologies in a Late Cretaceous mosasaur from the Netherlands

Evidence of osteomyelitis in the dentary of the late Triassic rhynchocephalian Clevosaurus brasiliensis (Lepidosauria: Rhynchocephalia) from southern Brazil and behavioural implications

Clevosaurus was a cosmopolitan Rhynchocephalia genus restricted to the Late Triassic and the Early Jurassic indicating that similar ethological conditions were already present at the beginning of the Mesozoic, during the initial radiation of the lepidosaurian clade.

Allometric growth in the skull of Tylosaurus proriger (Squamata: Mosasauridae) and its taxonomic implications

The partial and complete skulls of two subadult individuals of the mosasaurid Tylosaurus proriger from the upper Smoky Hills Chalk Member of the Niobrara Formation in Kansas are described and an allometric analysis is included to better understand proportional changes of the skull through growth.

Pathological survey on Temnodontosaurus from the Early Jurassic of southern Germany

According to the analysis, most observed pathologies in Temnodontosaurus are force-induced traumas with signs of healing, possibly inflicted during aggressive interactions with conspecifics.

Bite marks on an ichthyodectiform fish from Australia: possible evidence of trophic interaction in an Early Cretaceous marine ecosystem

Healed Bite Marks on a Cretaceous Ichthyosaur

The identification of a series of healed cuts and an associated gouge on the lower jaw of an adult Platypterygius specimen from the Lower Cretaceous of Australia constitutes direct evidence of bite force trauma sustained during the life of the animal.

Co-Ossification of Vertebrae in Mosasaurs (Squamata, Mosasauridae); Evidence of Habitat Interactions and Susceptibility to Bone Disease

Evidence for pathologies as the result of interactions with the mosasaur's habitat and the apparent susceptibility of certain kinds of disease affecting the skeleton as preserved in the specimens are discussed.


The size and distribution of the tooth marks indicate several possible producers of the bone modifications: a pilot whale or beluga-like cetacean, a terrestrial carnivore, a dusignathine or odobenine walrus, or a case of infanticide by a conspecific otariid.



Earliest record of the genus Tylosaurus (Squamata; Mosasauridae) from the Fort Hays Limestone (Lower Coniacian) of western Kansas

Abstract Fossil vertebrates are extremely rare in the Fort Hays Limestone member of the Niobrara Chalk in comparison to the rich variety of well-preserved fish, turtles, mosasaurs, pteranodons, and

New Data on Cranial Measurements and Body Length of the Mosasaur, Tylosaurus nepaeolicus (Squamata; Mosasauridae), from the Niobrara Formation of Western Kansas

Tylosaurus nepaeolicus is one of the least well known of the five species of mosasaurs that are recognized from the lower Smoky Hill Chalk Member (upper Coniacian) of the Niobrara Formation in western Kansas but the two species are closer in size than previously reported.

Late Cretaceous interaction between predators and prey. Evidence of feeding by two species of shark on a mosasaur.

The fragmentary remains of a mosasaur discovered in the Smoky Hill Chalk Member (Late Coniacian) of the Niobrara Chalk of Gove County, Kansas, U.S.A., preserve a number of injuries consistent with

Palaeopathology and injury in the extinct mosasaurs (Lepidosauromorpha, Squamata) and implications for modern reptiles

Three fossilized dentaries provide an insight into the healing of fractures in a major group of extinct marine predators, mosasaurs. The data has implications for modern day reptiles in which such

Anatomy and functional morphology of the largest marine reptile known, Mosasaurus hoffmanni (Mosasauridae, Reptilia) from the Upper Cretaceous, Upper Maastrichtian of The Netherlands

The skull is robustly constructed and is the least kinetic in the Mosasauridae and, with a tightly assembled palatal complex, provided greater cranial stability in this large-headed mosasaur.

Shark-bitten dinosaur (Hadrosauridae) caudal vertebrae from the Niobrara Chalk (Upper Coniacian) of western Kansas

Abstract The Niobrara Chalk in western Kansas was deposited on the eastern shelf of the Late Cretaceous Western Interior Sea during Coniacian through early Campanian time, hundreds of miles from the

Tooth morphology and prey preference of Mesozoic marine reptiles

The guilds present in six well-preserved faunas of the Jurassic and Cretaceous illustrate the structure of and changes in the large marine predator adaptive zone.

Explorations of the Permian of Texas and the Chalk of Kansas, 1918

The splendid skeleton of Dimetrodon gigas I collected in 1917 and sold to the United States National Museum has been mounted at last, and is one of the world's famous specimens. I do not know of a

The braincases of mosasaurs and Varanus, and the relationships of snakes

The hypothesis of a sister-group relationship of snakes and mosasauroids is discussed in the light of how hypotheses of homology, or synapomorphy, can be established on an empirical, i.e. testable and potentially falsifiable basis.
