Name: Chaoyangopterus zhangi

Name Meaning: Chaoyang Wing

First Described: 2003

Described By: Wang & Zhou

Classification: Avemetatarsalia, Ornithodira, Pterosauromorpha, Pterosauria, Macronychoptera, Novialoidea, Breviquartossa, Pterodactylomorpha, Monofenestrata, Pterodactyliformes, Caelidracones, Pterodactyloidea, Eupterodactyloidea, Ornithocheiroidea, Azhdarchoidea, Neoazhdarchia, Neopterodactyloidea, Chaoyangopteridae 

Chaoyangopterus is our first Chaoyangopterid - the group of pterosaurs most closely related to the famed Azhdarchids. Chaoyangopterus and others of its group actually did similar things - they were probably land predators that flew around to locate food, though Chaoyangopterids were probably more specialized - there were quite a few of them in one location, where as Azhdarchid had one genus per region - meaning that the Azhdarchids probably all did the same thing and Chaoyangopterids each did different things in their environment (except for the notable exceptions outside of this range). Chaoyangopterus was one of the clustered ones, living about 120 million years ago in the Aptian age of the Early Cretaceous in the Jiufotang Formation of Chaoyang, China - making it the titular pterosaur of the region. It is known from a good portion of the skeleton. It had a wingspan of nearly 2 meters long, making it a rather smallish to medium sized pterosaur, it had a massive head, short wings, and small torso, like others in its general group, and probably had a crest on its head like others in its group for display. It also had no teeth, so it would have grabbed (smallish) prey and picked it up with its beak.

Name: Lacusovagus magnificens

Name Meaning: Lake Wanderer

First Described: 2008

Described By: Witton

Classification: Avemetatarsalia, Ornithodira, Pterosauromorpha, Pterosauria, Macronychoptera, Novialoidea, Breviquartossa, Pterodactylomorpha, Monofenestrata, Pterodactyliformes, Caelidracones, Pterodactyloidea, Eupterodactyloidea, Ornithocheiroidea, Azhdarchoidea, Neoazhdarchia, Neopterodactyloidea, Chaoyangopteridae

Lacusovagus is another Chaoyangopterid, but interestingly enough this one comes from the Crato Formation of Ceara, Brazil, dating to the mid-late Aptian, early Cretaceous (more or less 120-122 million years ago). It’s only known from a nearly-flattened skull, but there are Chaoyangopterid neck vertebrae from the same formation that may also belong to it. Its jaws were long, toothless, and crestless. The skull was unusually wide, with “zig-zagging” sides, and probably had a fairly deep nasoantorbital fenestra behind the beak. Its wingspan is estimated at 4.1 meters, making it the largest Chaoyangopterid and one of the largest pterosaurs of the Crato Formation.

Name: Jidapterus edentus

Name Meaning: Jilin University Wing 

First Described: 2003

Described By: Dong, Sun & Wu

Classification: Avemetatarsalia, Ornithodira, Pterosauromorpha, Pterosauria, Macronychoptera, Novialoidea, Breviquartossa, Pterodactylomorpha, Monofenestrata, Pterodactyliformes, Caelidracones, Pterodactyloidea, Eupterodactyloidea, Ornithocheiroidea, Azhdarchoidea, Neoazhdarchia, Neopterodactyloidea, Chaoyangopteridae

Jidapterus is another Chaoyangopterid, from the Jiufotang Formation of Liaoning, China, living about 122 million years ago, in the Aptian age of the Early Cretaceous. It is known from most of the skeleton and its large skull, which shows that it had a toothless and long beak as well as large cavities in its head that made it lighter and connected the nostril with the rest of the skull’s airways. It was a little small, with a wingspan of only about 1.7 meters in length, and it probably ate small vertebrates on the ground, grabbing them out of the forest floor with its long pointed beak.

Name: Eopteranodon lii

Name Meaning: Dawn Toothless Wing

First Described: 2005

Described By: Lü & Zhang

Classification: Avemetatarsalia, Ornithodira, Pterosauromorpha, Pterosauria, Macronychoptera, Novialoidea, Breviquartossa, Pterodactylomorpha, Monofenestrata, Pterodactyliformes, Caelidracones, Pterodactyloidea, Eupterodactyloidea, Ornithocheiroidea, Azhdarchoidea, Neoazhdarchia, Neopterodactyloidea, Chaoyangopteridae

Eopteranodon is an Azhdarchoid perviously thought to be a Tapejarid - hence its position in the Pterosaur Ptuesday lineup - but now is thought to be a Chaoyangopterid, another group of crested, long-jawed pterosaurs, except more like the Azhdarchids in general behavior, with similarly long legs and necks, just smaller bodies. They were probably highly specialized as well, given that they all lived in similar locations while Azhdarchids lived in multiple different locations. Eopteranodon in particular lived in the Yixian Formation of Liaoning, China, living about 124.6 million years ago, in the Aptian age of the Early Cretaceous. It is known from multiple specimens, and had a wingspan of about 1.1 meters. It is one of the earliest known toothless pterosaurs, hence the name, and not really closely related to Pteranodon at all. It was a strong flier, and it probably ate fish and small animals in its forested environment.
