This week's title, shared with the Vintage Dinosaur Art pool by Sharon Wegner-Larson, is Dinosaurs and Prehistoric Animals by Graham Wellfare, with illustrations by Robert Ayton. Ayton is an other veteran illustrator; his focus for most of his career seems to have mainly been on non-fiction titles, with some fairy tales tossed in for good measure. He's particularly known for his work with Ladybird, a British publisher of childrens' titles.
Published in the late seventies, the title does reflect some dinosaur renaissance ideas, for instance the theropod origin of birds. But much of the artwork is still rooted in the classic portrayals of dinosaurs.
Oddly enough considering the upright posture in the last image, this page of scale drawings portrays Tyrannosaurus as walking with the correct posture.
No old dinosaur book is complete without a few Charles R. Knight homages, and here's a very Knightish Protoceratops. Not a shameless tracing as so many artists were gulity of, but clearly based on Knight's famous Protoceratops painting for the Field Museum.
And of course, our friends the pterosaurs get their time in the spotlight, and if you click the image to get a larger view, you'll read that the book held with the view that pterosaurs were primarily gliders, and idea that gave way to our modern view of pterosaurs as achieving true powered flight.
This next illustration of a mounted "Brontosaurus" made little bells go off in my head. Check out the cover of this Peter Zallinger book. Same angle, same pose! I suspect that both are based off of an actual mount somewhere - anyone know where? This one also looks similar - though from a different angle, it's holding its neck stiff like the other two. (See comments for the ID!)
Ayton's nephew has written a biography of him, which is available at Issuu.com. Big thanks to Sharon for sharing these with the pool!
