Skeletal reconstructions of Dinosaur Park Formation caenagnathids. Skeletal reconstructions of Citipes elegans (left), Chirostenotes pergracilis (middle), and Caenagnathus collinsi (right), showing variation in skeletal representation and body size. Previously referred material is indicated in white and newly referred material is indicated in red for each taxon. Blue asterisks indicate elements that have been histologically sampled for each taxon. Citipes elegans: dentaries, metatarsal IV; Chirostenotes pergracilis: dentaries, tibia; Caenagnathus collinsi: pubis.
Megapnosaurus is a coelophysid theropod dinosaur from the Early Jurassic Period of Africa. It was a lightly built bipedal carnivore that grew to just over 2 m long and 13 kg in body mass. Its close relation to Coelophysis has caused some confusion in classifying the genus - it had a slender build and curved S-shaped neck, but was more robust. Comparisons between the scleral rings of Megapnosaurus and modern birds and reptiles indicate that it may have been nocturnal.

Melanorosaurus readi restoration, • Based proportionally on a skeletal reconstruction by Scott Hartman. [1] • The coastal setting is not meant to imply that this animal lived near the coast. It was chosen for artistic reasons. • The colours and/or patterns, as with nearly all reconstructions of prehistoric creatures, are speculative. NOTE: I often update my images. If you want to have any of my images on a website, please (if possible) don’t host/save it to the website server. I’d prefer it if the image's Wikimedia URL is used. This means that if I update an image, it will be updated on the site as well. Thanks.
