I grew up on Land of the Lost, a cheesy kids show in the 1970s in which cavemen were chased by dinosaurs and well, something called sleestaks. OK, so they never purported to be accurate, but as a kid, you want to believe anything that is adventurous and fun.
Scientists have also been quick to pull the trigger on their ideas about life in the past. These days, scientists are still trying to get it right when it comes to depicting fossil creatures. The process will never end.
