The Bichir Handbook is a book written by science communicator and graphic designer Joshua Pickett from Salisbury, England, [1] about living fossil fishes known as Polypteriformes (bichirs), found throughout west and central Africa, and formerly South America.

Mallon and Anderson postulated that Ankylosaurs and Ceratopsids may have partitioned the herb layer in the Dinosaur Park Formation, or that Ceratopsid feeding height was slightly higher. [21] As well as suggesting that the Ornithopods might have made room for the passing Ceratopsid herds by rising up to avoid ecological competition.
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.
The Houston Chronicle stated, "this reference work for the serious student combines succinct scientific descriptions with superbly rendered color illustrations". [1] In a positive review for Palaeos, M. Alan Kazlev wrote, "This is a very good non-technical introduction to prehistoric vertebrates" and "it is the sheer number and diversity of creatures covered here, that makes this book so ...
Diictodon is an extinct genus of pylaecephalid dicynodont [5] that lived during the Late Permian period, approximately 255 million years ago. Fossils have been found in the Cistecephalus Assemblage Zone of the Madumabisa Mudstone of the Luangwa Basin in Zambia and the Tropidostoma Assemblage Zone of the Teekloof Formation, Tapinocephalus Assemblage Zone of the Abrahamskraal Formation ...
