The South African Mosasaur is an armored sea creature washed up on a beach. This creature's history is a bit murky. It's reported to have washed up on a South African Beach in 1931, but since this is a color photograph that's unlikely to be the case. If anyone has additional information we'd be glad to receive it. We note that it appears to look very much like a Mosasaur, a sea creature supposedly extinct millions of years ago.
