In Depth When Alexander Kellner found what was thought to be a Pteranodon, he realised that morphological differences in the specimen meant that it was not a match. Kellner then compared it to the next closest pterosaur and in the process made the exciting discovery that it was not an individual of this genus either … Read more
In Depth Ornithostoma was once considered to identical to Pteranodon, although modern thinking has it recognised as its own genus. Unfortunately Ornithostoma has suffered from the wastebasket effect with numerous poorly preserved remains being attributed to it. Although not much is known for certain, the toothless beak of Ornithostoma likely indicates a fish eating piscivorous … Read more
In Depth Multiple species and the differences between male and female. Much like the pterosaurs Pterodactylus and Rhamphorhynchus, Pteranodon has suffered from the wastebasket taxon effect. This is because at the time of its discovery it was the only known toothless pterosaur, and as such any remains that suggested a toothless pterosaur were almost automatically … Read more
