Having a lot of fun creating these.
Mahamba I've taken on board the idea of a giant crocodile but also a large freshwater relative of the mesiosaur.
I have taken huge liberties with the other two Cryptids.
The Lizard man is a combination of similar Cryptids, I like the idea of the same species popping up in different areas, seems more realistic to me. So The Loveland Frog, Lizard Man, Cherufe, Reptilian and perhaps even chupacabra become the same creature.
Mammoth Albus, is almost completely invented by me for my story 'Shadow of the Yeti' Mammoths have popped in in Crypto-zoology but again why just have a normal mammoth un-hampered by time? I've always liked the idea of a white mammoth, hence the name, and threw in the 4 tuskes of the gomphotherium elephant another extinct animal.
