Did you ever wonder exactly just how dinosaurs performed the intercourse work? Don’t fret for those who haven’t figured it down yet – the situation stays a puzzle for science, although progress has been made. The real question is addressed by Brian Switek when you look at the April version of Scientific United states .

Dinosaurs, the well-known reptiles that are giant the biggest animals ever to walk the planet earth, ruled our world for 135 million years, & most became extinct 66 million years back. Until recently, biologists could maybe maybe perhaps not inform the intercourse of any dinosaur from the fossilised keeps. Nevertheless, a breakthrough had been manufactured in 2000, each time a fossil of Tyrannosaurus rex with a broken thigh bone tissue had been noticed to own a medullary bone – a layer of calcium-rich muscle within the shaft of long hind-leg bones that is developed in certain types of expecting feminine wild birds as a shop of garbage for producing eggshells. Therefore fossils of expecting dinosaurs that are female now be identified, but that’s in terms of it goes.

Paleobiologists understand little about dinosaur organs that are sexual soft muscle is seldom preserved in fossils. Did male dinosaurs have actually a penis and feminine dinosaurs have vagina? Continue reading “Wild wild Birds take action, bees do it – but how did T Rex take action?”
