I wonder why africa is completly free from any Alligatoridae. You have them in the americas and one species in China. Africa and Latin America were once connected. You have true crocodilians in eurasia, africa, australia, the americas. Alligator sinensis proves, that the family of the Alligatoridae evolved before pangea breaked apart and it is obvious that they had to inhabitate africa to reach asia (see Ctenopoma and Channa/Parachanna). The same problem can be seen at member of the Boidae. You have boas mainly in the americas while the old world is inhabitated from python. But there are 3 species of boas on madagascar. Were true crocodilians able to push the alligatoridae into extinction in africa and most of eurasia? Why didn´t that happen in the americas?

Could be, but they seem go have no influence on the crocodilians in africa. Amd similar animals inhabitated south american water ways.
lol @ beex! I had a similar answer...
Maybe the environs are prohibitive to the alligators and they wouldn't flourish there for whatever reason. Maybe there are alligators there, they just look like crocodiles so they get clumped in with the rest... I don't know, just throwing out ideas...

It would also be interesting to know if any polypterids remained in south america. They are known as fossils in brazil and bolivia.
common ancestors, extinctions and evolution.......
off subject, but Darius, your lack of social skills makes me wonder if perhaps you have been diagnosed with asperger's? Your forum interactions show many of the classic symptoms.
