Abstract
The cranial growth of C. glareolus was investigated using 444 captive bred individuals, aged from 5 to 680 days. Three growth patterns of skull characters were found: (1) rapid growth in the first decade of age, followed by a very slow change or stabilisation (width of molar M1 and length of maxillary tooth row), (2) long period of flat growth (length of mandibular tooth row and length of mandibular diastema), and (3) long period of initial growth followed by the plateau phase (length of nasalia and length of foramen incisivum). The measurements of skull characters correlated best with body weight, whereas correlations with body length or individual age were less expressed. Out of 20 skull characters tested, the strongest correlation with animal age and body weight was observed in the length of cranial (upper) diastema. Other characters, which correlated with animal age, were the length of nasalia and the length of molar M1. In captive bred individuals, fluctuations of body weight and skull measurements w...
