query: What was the reason for mounting the slender limbs of Dimetrodon dollovianus instead of the correct, stockier limbs of Edaphosaurus on the American Museum of Natural History's composite specimen?
answer: Because at the time, "Naosaurus" (what Edaphosaurus was then called) was thought to be a close relative of Dimetrodon, the slender limbs of Dimetrodon dollovianus were used in the composite mount instead of the correct, stockier limbs of Edaphosaurus.
