Dinosaurs living in the dark

28 January 2018

At https://archaeologynewsnetwork.blogspot.co.uk/2018/01/fossil-bone-tissue… … Dinosaurs dug out of rocks in Victoria State, Australia, more than 120 million years of age, had to deal with prolonged periods of darkness and below freezing temperatures – according to a new study in Scientific Reports (January 2018). Problem with that assumption seems to be the difficulty plants might have to flourish in darkness as these were herbivores. Do plants grow in complete darkness and was Australia really at the pole 120 million years ago? Examination of bone micro structure of the fossil dinosaurs shows rings in the bone – somewhat akin to tree rings in trees. This is said to have helped them to determine age – whilst bone fibre and blood vessel density also haped determine annual growth rates.
