how is that possible? how could they survive without dinosaurs eating them? this interests me. are there any sharks that are alive today that are exactly the same as they were then or did they evolve? thanks for any help.

It's really simple actually. Dinosaurs live on land, Sharks live in water. That's why the two species don't interact. Sharks haven't really evolved however. You can see in an ancient fossil on a shark and a present day shark that the bone structures are almost the same. They are still filled with cartilege and still have the same teeth structure. The only exception would be Megladon. This is a giant prehistoric shark who's teeth are around 5 times the size of present day sharks and they can grow around the same length as a T. Rex. Today, we have some interesting looking sharks as well. Just look at the hammerhead or the sawshark.

Of course they are alive for example the great white shark only they were much bigger back then,and how could possibly every single shark get eaten please,thats as stupid as asking how come cows dont go extinct when people kill and consume their meat every day.animals constantly reproduce.so when one dies another one is born.Use your brain :D.

It's all about theories and some theories say that sharks and crocodiles and some kind of lizards lived while the dinosaurs did and some theories even say that lizards are descendents of some dinosaurs

Probably because the shark could eat the dinosaur, search megaladon on google or something and there is an ancient japanese shark found off the cost of i believe costa rica that has been the oldest one so far

I dont think theyd eat them since most dinosaurs were on land and sharks can live deep in the oceans...
