Howdy all, I've seen a lot of fossils from Alligator americanus, but none from Crocodylus americanus, yet both are present in the modern day. Did C. americanus emerge later than A. americanus or are fossils of C. americanus being labeled as A. americanus for convenience?

Howdy all, I read somewhere that Thecachampsa americana is a synonym for Crocodylus americanus, at least in reguard to thecachampsa fossils found in pleistocene deposits in Florida. Is this true?

I had a question about the ID of croc teeth from the Solo River, Java, Indonesia. While the bigger tooth is more easily identifiable as Crocodylus siamensis (syn. Crocodylus ossifragus) just on the size and shape, I was unsure about the smaller one. Croc teeth from the Pleistocene deposits (not sure what formation it's called) are usually just sold as Crocodylus ossifragus, but Gavialis bengawanicus also appears to have been present. The smaller tooth does have prominent fluting, but I'm not sure if that's even a distinguishing feature. I haven't really seen a whole lot of Crocodylus teeth, fossil or extant. Not sure if smaller teeth from this region are even identifiable. If anyone has any knowledge of distinguishing gharial from crocodile, help would be appreciated. Measurement in centimeters. Last image here is just a comparison with a Thecachampsa americana (left) from Bone Valley, Florida.
