From Science Daily:
By comparing the skulls of 26 different Nimbadon individuals that died in the cave at varying stages of life the team has been able to show that its babies developed in much the same way as marsupials today, probably being born after only a month’s gestation and crawling to the mother’s pouch to complete their early development.
Dr Black notes that the Nimbadon skulls also reveal that early in life, the emphasis of its growth was on the development of bones at the front of the face, to help the baby to suckle from its mother. As it grew older and its diet changed to eating leaves, the rest of the skull developed and grew quite massive by way of a series of bony chambers surrounding the brain.
