of interclavicles, Tschopp and Mateus (2013) proposed that the furcula is a transformed and divided interclavicle, rather than a fused clavicle. In folklore Superstitions surrounding divination by means of a goose's wishbone go back to at least the Late Medieval Period. Johannes Hartlieb in 1455 recorded the divination of weather by means of a goose's wishbone, "When the goose has been eaten on St. Martin's Day or Night, the oldest and most sagacious keeps the breast-bone and allowing it to dry until the morning examines it all around, in front, behind and in the middle. Thereby they divine whether the winter will be severe or mild, dry or wet, and are so confident in their prediction that they will wager their goods and chattels on its accuracy.", and of a military officer: "This valiant man, this Christian Captain drew forth out of his doublet that heretical object of superstition, the goose-bone, and showed me that after Candlemas an exceeding severe frost should occur, and could not fail." The Captain also said, "Teutonic knights in Prussia waged all their wars by the goose-bone; and as the goose-bone predicted so did they order their two campaigns, one in summer and one in winter." The custom of two persons pulling on the bone with the one receiving the larger part making a wish developed in the early 17th century. At that time, the name of the bone was a merrythought. The name wishbone in reference to this custom is recorded from 1860. See also Bird anatomy References Bird anatomy Dinosaur anatomy
