Putative behavioral reflexes of fossilization. Can you name any dinosaurs?. Do you know what they looked like or how they moved?. Scientists have been able to tell us many things about organisms (such as dinosaurs) that lived millions of years ago.. Can you name any dinosaurs?. Do you know what they looked like or how they moved?. Scientists have been able to tell us many things about organisms (such as dinosaurs) that lived millions of years ago.. Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. Fall 2012.
