blood in amber

At https://phys.org/print410453784.html … blood preserved in amber, the fossilised red blood cells of monkeys.

At https://archaeologynewsnetwork.blogspot.co.uk/2017/03/new-research-dispr… … Palaeontologists have used skulls to delineate how much movement certain animals had in their necks – such as birds, dinosaurs, alligators etc.

Even though these animals had visually similar necks it was only under the microscope that differences could clearly be see.

                               Apparently, large gaps do not necessarily mean lots of nodding of the head (although it is not an unreasonable guess). Looking at skulls and joints through a microscope allowed scientists to see that some of them looked like fluid filled cavities rather than cartilage.
