Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process. However, recent studies of feathered dinosaurs and skin impressions have shown the colour of some species can be inferred through the use of melanosomes , the colour-determining pigments ...
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.
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.
Polypterus senegalus, commonly known as the Senegal bichir, gray bichir or Cuvier's bichir, is an African species of ray-finned fish in the bichir family, Polypteridae.It is a typical example of polypterid fishes, as most of its defining physical features are common across the genus, such as its ancient, lungfish- or arowana-like appearance, the ability to breathe atmospheric oxygen, and its ...
P. polli is an “upper-jaw” bichir, meaning its maxilla protrudes further out than its mandible. It has a maximum recorded length of 12.6 inches (32.1 cm). [2] It can be distinguished from other bichirs by its dull gold body color, greenish-yellow fins, and reticulated body pattern with light-colored “polka-dots” toward the base of the tail.

The dinosaur collections made over the past decade during the Hell Creek Project yielded new information from an improved genus-level collecting schema and robust data set that revealed relative dinosaur abundances that were unexpected, and ontogenetic age classes previously considered rare.
