Hexaaluminate compounds were effective in maintaining large surface area.
It maintains large permanent bases throughout Europe and Asia.
Giant pandas have powerful jaw muscles and large molars, handy for eating bamboo.
Although overall skull length is about equal in both species, molars of Megalomys are smaller than those of "Ekbletomys" and incisors are larger, reflecting relatively large molars and slender incisors in "Ekbletomys" and the reverse in Megalomys.
Also, river otters have large molars used for crushing hard objects, such as the shells of molluscs.
These large molars arise from fusion of different molar tooth germs during development.
Yet, for a tiny body size, Nannomys display extremely large molars.
To examine whether the abnormally large molars developed from a single tooth germ or were created by fusion of several molar tooth germs, micro CT analysis was performed.
This suggests therefore that the large molars have formed from a fusion of first and second molars with a anterior supernumerary tooth.
Wise mutant maxillary molars were also very large and had similar root patterns to Lrp4 mutants, suggesting that their large molars were formed by a similar fusion process (Figures 4J 4L).
