Smilodon: a myth among many people. Smilodon was a very successful felid. At its height, Smilodon ranged from the glaciers of North America to the bottom of South America (1). But then, it went extinct. How did this happen?
Because of a radically changing environment. As the megafauna herbivores began to go extinct, the specialization of the Smilodon contributed to its demise (1). Its size (2) also caused the Smilodon's demise. Although Smilodon was very opportunistic, as the colonization of South America demonstrated (3), Smilodon depended on one thing: large amounts of megafauna. Human hunting, climate change, and hyperdisease overwhelmed the prey species (4). With most of the prey species gone, the whole ecosystem collapsed. The inability of Smilodon to hunt smaller species (1), combined with fierce competition among all the megacarnivores (5) cuased Smilodon to go extinct.

It would be good if you mentioned that the genus Smilodon is extinct in your overview articles above. You don't give any info here about when Smilodon species lived or when it died off. Keep clear that Smilodon is a genus, not just one species. What do you mean by "a myth among many people?"; What do you mean by the colonization of South America? How were Smilodon opportunistic? (Smilodon species colonizing South America?) You have given very clear cut causes for extinction but you should be clear that causes are not fully understood and research is still investigating this. What is reference 5?? Spelling error: cuased.
