All kinds of stuff

[Brontosaurus]

The Nursery I work for just got a shipment of cacti and neither they nor the grower they bought it from knows what it is. If you could be any help in IDing them I'd be quite grateful.

Hello,
my guess is;
Picture 1: Some kind of Cereus (most probably South American Cereus =Column cactus). Obviously not all the very same. Maybe Hybrids?
Picture 2: Could be Echinocactus grusonii
Picture 3: I have not good guess here
Picture 4: Mammillaria, but obviously differenbt ones or hybrids?
Picture 5: Notocactus, could be N. schlosseri
Picture 6: An Opuntiode, most probably Cylindropuntia spec.
Picture 7: Notocactus, very similar to picture 5, most probably the same.

Best regards
Gerd

Is the first picture marginatocereus marginatus?

Picture 3 is a Mammillaria also, not sure which.
