Interesting study, however, every scientist should stay as far away as possible from #generativeAI! It is literally just making things up with little to no control over the output. No morphology, soft tissues nor anything else can be "reconstructed" or "augmented" with genAI.

I finally got this working. Pro & uropatagium to follow. Side note, while I'm aware of hypotheses about actinofibril function, I'm not a fan of the trope of pterosaur wing membranes shrinking to almost nothing when grounded rather than just being allowed to fold, even a little bit.

For #FossilFriday, here's some #paleoart of a casual afternoon in the Early Cretaceous Wealden group, with iguanodonts, tyrannosauroids, polacanthids and sauropods making a mess of a watering hole. The mashed-up muds left by these animals can be found to this day in Wealden rocks. #dinosaurs #sciart
A blue-skied landscape set around a watering hole in the Early Cretaceous. Three large, subtly-striped iguanodonts are emerging from the water while white flying reptiles flap past them. They approach a group of smaller iguanodont species with red-orange backs and pink-grey hides, who are drinking from the water. Seen between them is the front half of an armoured dinosaur, a polacanthid, walking by. The group of small iguanodonts stands on a churned-up mess of brown mud, the product of many heavy animals coming to drink. In the mid-foreground is a small, gold tyrannosauroid with its head tilted back to trickle water down its throat. Several small, bird-like oviraptorosaurs sneak along the water margin in the lower left. Dinosaurs of opposing size - two enormous, long-armed brachiosaurs 
- stand in the far distance, in front of a sparse forest.

Illustration of an immature male American Redstart perched on a branch in front of a mottled green background. He has his tail fanned, and his head turned to preen the feathers above his right hip. He has a greenish back, white flanks, and that big fanned tail is dusky gray-brown with broad yellow patches on either side. His head is a soft gray, mottled by little flecks of adult-like black feathers.

the same image, repeated twice. one image is just a scenery, the other includes text and very complex arrows pointing to each other explaining the relationship between substrate, plankton, predators and other elements in a marine ecosystem. 

the scenery is of a seafloor split into 4 horizontal slices depicting 4 time frames. the first one is an ediacaran scene filled with frond-like organisms attached to the seafloor. the second one shows fewer fronds and more things crawling on the seafloor. the third shows a sponge reef, with herbivores and active predators lurking in the sediment. the fourth shows a very active cambrian period scene with swimmers and burrowers.
