Ron Embleton was the Leonardo Da Vinci of dinosaurs having sex. The dude was extremely proficient at painting two dinosaurs engaged in scaly coitus.
The dinosaur fucking was only a small part of a career that spanned five decades in various mediums drawing and painting book covers and adventure strips, but the internet seems to be fixated mostly on the dinosaurs having sex that he painted for a 1988 Magazine.
Ron Embleton died shortly after the issue was printed, meaning the dinosaurs having sex may very well have killed him
