Wich shark species are these 4 teeth?

[Praefectus]

Where are these from? Are they all from the same place? Can you post some better pictures? Thanks.

 

 

1 and 3 are Carcharodon hastalis lower teeth. I think 2 is Scapanorhynchus and 4 is Anotodus retroflexus. I'm not as sure about 2 and 4. @MarcoSr What do you think?

Definitely need some better pictures and some idea of where they are from and a time period.  Size would also be helpful.  2 could be a a good number of genera/species depending on the time period.  I can't see the labial root/crown interface area on 4 which is needed to determine A. retroflexus.  Actually if one of the four teeth were A. retroflexus 3 looks the closest from the pictures.

Definitely helps.  1,3, 4 look like C. hastalis.  2 is a sandtiger probably Carcharias.
