Do you know this feeling when your head is full of ideas but you have not the time to realize them all, and even your sketchbook can’t help you.
Damn All Yesterdays, what have you done with me.
Here you see two ideas for possible pterosaurs behavoirs:
1. A Raeticodactylus/Caviramus sitting on a bough and spear a primtive frog (Czatkobatrachus) on a branch/thorn for later. The concept was suggested by ~KingOvRats and it’s absolutely worthy a realisation.
2. Perhaps you wouldn’t recognize it immediately but this is a part of the back of an titanosaur (Maybe Dongbeititan?). Since I knew that some sauropods have osteoderms I wonder what they could be used for. The calcium storage idea was very interesting and I think they are not completly useless for defensive. Here I speculate that small pterosaurs (in this case Nemocolopterus) use the osteoderms as platforms for their nests, build by clay, saliva and excrements. No bigger animal today have such osteoderms what makes it impossible to proof my idea. But when some sauropds, like modern giraffs, standing in sleep, and when the incubation of the pterosaurs is short enough, it would be a perfect place to rice babys. Most predators wouldn’t try to reach the back of this titans and because of the constantly moving nesting ground there is no risk to overextend the food sources.
In addition the sauropod would be warned of bigger predators and parasites are no longer a problem.
