Amali is a dinosaur-like cryptid, reported from lakes of Gabon, similar to the Mokele-Mbembe. It's a amphibious creature with three claws, footprints the size of frying pans.
The adventurer Trader Horn allegedly discovered a cave painting of an Amali, chiseled it out, and sent it as a gift to U.S president, Ulysses S. Grant. If true, this incident most likely occurred in the early 1880s, after Grant left office.
