Andrillona of Petersburg do a nice range of paleolithic animals, mammoths, cave lions, megaloceros and are bringing out wolves, woolly rhinocerous and bears.

Hello Graham, can you provide a link to the prehistoric animals? I can't seem to google them.

Thanks.

I would definitely buy sets of pack animals, cattle, and bison. (Separate sets, not combined.) I also like the idea of combined sets based of geography, although to be honest I would probably only buy a single set.
