As part of their Dinosaur Valley attraction, Nong Nooch Tropical Garden installed statues of the illustrations inside the book, each exceeding 1.5 metres in length.

Cladistia is a subclass of bony fishes whose only living members are the bichirs of tropical Africa. [1] Their major synapomorphies are a heterocercal tail in which the dorsal fin has independent rays, and a posteriorly elongated parasphenoid.
The maximum recorded length of P. palmas is 35.3 cm (13.9) inches, although lengths of around 30 cm (11.8 inches) are much more common. [4] It can be distinguished from other similarly-sized bichirs such as Polypterus senegalus and Polypterus polli by its bright gold coloration, speckled pattern, and dark transverse barring.
