First time I've heard anybody claim crocodiles are dinosaurs.
Because they are not. Dinosaurs and crocodiles are both archosaurs. But to claim one group is descended from the other is incorrect in much the same way as I am not descended from my brother.
Crocodiles are also not lizards. Lizards split with archosaurs before dinosaurs and crocodiles split. So crocodiles are not lizards in the same way as I am not descended from my cousin.
Maybe YOU'RE not descended from your brother and your cousin, but nothing in biology precludes you being descended from your brother and your cousin. (It would have to be a half-brother though.)
