the jaws, carinae are restricted to the base of the teeth and would not have been used to tear prey. The back teeth, however, share the same general characteristics as those of most other theropods, suggesting that they served a similar function in Masiakasaurus such as cutting and slicing. Several feeding behaviors have been proposed for Masiakasaurus on the basis of its unusual dentition. Because the front teeth would have been well suited for grasping, Masiakasaurus may have consumed small vertebrates, invertebrates, and possibly even fruits. Growth In 2013, Lee and O'Connor observed that Masiakasaurus would be a good subject for an analysis of theropod growth, considering that there is an abundance of fossil material to examine from a broad range of ontogenetic stages. The study showed that Masiakasaurus grew determinately, and reached full maturity at a small body size. Competing theories that Masiakasaurus specimens represent the juvenile form of a larger-bodied theropod were not supported by the data. Masiakasaurus took 8 to 10 years to grow the size of a large dog. This indicates a rate of growth that is 40% slower than that of comparably sized non-avian theropods, a finding that is supported by the unusual prominence of parallel-fibered bone which is known to be associated with relatively slow growth. However, individuals in this genus grew 40% faster than crocodylians. Lee and O'Connor noted that the evolution of slow growth gave this dinosaur the advantage of minimizing the nutritional investment allocated toward structural growth while living in a semiarid and seasonally stressful environment.
