[Development of the skeleton in the sheep and the goat. IV. Osteogenesis of the cranium].
1. The osteogenesis of the cranium was studied on a precisely dated embryological and postnatal material from merino-sheep and goats (crossbreed). 2. The order and duration of the appearance of ossification centers were determined (see Fig. 6). 3. It was noticed that, in small ruminants, the beginning of cranial ossification indifferent to other parts of the skeleton is not staged in time. Sexual dimorphism was only manifested by larger proportions of the male fetuses. An exception was noted only in os interparietale, which in male fetuses appeared 4 to 5 days later in male fetuses. 4. The cranial bones of small ruminants, showed a high degree of ossification at birth.
