Palaeontologists are those who have dedicated a portion of their lives to the study of ancient organisms and environments. They are able to interpret how creatures may behave, based on their morphology.

The first record of Megalosaurus was the end of an isolated fragmentary femur (sadly now lost) described in 1763 by Brookes. He gave it the comedic name of Scrotum humanum due to its unfortunate shape. Later in the 1700s, a partial jaw was discovered that was eventually named Megalosaurus by William Buckland in 1824. It was considered to be some kind of lizard or crocodile and in 1842 Richard…

Palaeontologists come in many varieties. Below are some suggestions for traits, ideals, bonds, and flaws that a palaeontologist may have. d8

Huge Beast (Dinosaur), Neutral AC 11 + the spell’s level + 2 (Ankylosaur only) Initiative +0 (10) HP 60 + 10 for each spell level above 6 Speed 40 ft.

“Meg-ah-low-sore-us” (Great reptile) This is a beast that I’d read lots about in the ancient libraries of my university – the first dinosaur fossil ever described by scientists. When we first sighted it, I was all giddy with excitement. But, nothin’ prepared me for how magnificent and deadly it was. It attacked without warnin’ and unleashed a flurry of claws, teeth, kicks, and tail swipes. We…

Pluvenn concept sketches Since we first learned of the creatures that existed before us, we have asked the questions “ What if the [non-avian] dinosaurs hadn’t died out? ”, “ What would they have evolved into? ”, and “ What if dinosaurs became humanoids? ”. Many people tried to imagine intelligent bipedal (walking on two legs), humanoid-like, scaly dinosaurs. This idea has persisted in human…

Oviraptor was a small theropod at about 5 ft. long, with well-developed feathered plumage, a toothless beaked jaw, and a crest on the middle of its skull. Its legs and arms were quite long for its size with elongated fingers and large claws. By contrast, its tail was quite short for a theropod and ended in a pygostyle (the vertebrae were fused together), an adaptation that has been extended to…

We hope that you found the information in this chapter both interesting and digestible. With it, you could take the first steps to becoming a palaeontologist as a full-time career or explore collecting your own fossils. There is so much more that we would love to discuss and explain, but it’s time to get to the meat of this book – the roleplaying content. Let’s get some dinosaurs into your games!

Wondrous item, RARE Appearance: This six-sided dice has the visages of six different large dinosaurs carved into each face. Once rolled, a strange bellowing noise can be heard in the distance. Rules: The first time that this dice is rolled each day, it summons a dinosaur that matches the carved visage of the face it rolls to. The dinosaur is summoned somewhere within a 1 mile radius and is…

The behaviour of a herbivore that can flee a predator (i.e. a Gallimimus) and one that can’t (i.e. an Ankylosaurus) is very different when threatened. Use your own judgement when determining whether a creature is ‘fast’ or ‘slow’, but we recommend treating any herbivore with a speed of 20 ft. or less as ’slow’. For very large and slow sauropods, you can roll on either the Large Herbivore or…

Deinocheirus is a giant ornithomimosaur from the Late Cretaceous (70 million years old) Nemegt Formation of Mongolia. A relative of Gallimimus, Ornithomimus, and Struthiomimus, it is both the largest and most bizarre member of its family. Design Philosophy Life is diverse. We find that the current 5.5e system of normal, proficiency, and expertise for saves/skills/attacks/etc. calculations based…

“CAR-CHAR-OH-DON-TOE-SORE-US” (shark tooth reptile) There are some beasts that really do straddle the line between animal and monster. We heard it first – the thunderin’ footsteps and gurglin’ deep growls. We could feel the sounds deep in our chests. Cowerin’ in the undergrowth, we used some subtle magic to mask our scent and a few members of the party whispered prayers to their deities. When we…

We find that the current 5.5e system of normal, proficiency, and expertise for…

While I don’t deny the compliment, I assure you, I’m more akin to a god than a “pretty kitty.” —Brother of Shadows, Cat Lord Animal lords are the immortal spirits of legendary animals. They serve as the divine protectors of animals of their kind, and they appear as hybrids of humanoids and the animals they defend. They frequently change into giant, idealized versions of the animals they’re…

Iguanodon is an iguanodontian ornithischian dinosaur from the Early Cretaceous (126-120 million years ago) of Europe. The second dinosaur to be described and named; it is the most famous example of how our understanding of dinosaurs has changed over time. Design Philosophy Life is diverse.
