Teeth eruption pattern in Cantabrian chamois Rupicapra pyrenaica parva

A teeth eruption pattern for Cantabrian chamois Rupicapra pyrenaica parva (Cabrera, 1911) was presented (Cantabrian Mountains North of Spain) Permanent teeth eruption order was as follows: (M(1) M(1)) M(2) M(2) I-1 M(3) M(3) (PM(2) PM(3)) (PM(1) PM(1) PM(2) PM(3) I-2) I-3 I-4. The eruption time was: M(1) and M(1) at 2-3 months, M(2) and M(2) between 9 and 13 months, M(3) and M(3) between 22 and 25 months. Lower and upper premolars and I-2 emerged at 25-29 months. I-3 emerged at 36-37 months, and the last tooth erupting was I-4, between 36 and 46 months. The early eruption in Cantabrian chamois in relation to other chamois subspecies was discussed, and it was suggested that possible advantages relate to chewing efficiency and a wider age-related use of vegetation.
