Last time, we took a very quick look at YPM 1910, a mounted skeleton that is the holotype of Camarasaurus (= “ Morosaurus “) lentus , in the dinosaur hall of the Yale Peabody Museum. Here’s the whole skeleton, in various views. Skip down to the bottom for the science; or just enjoy the derpiness. First, in anterior view: Here’s a more informative right anterolateral view.

Matt’s harsh-but-fair “Derp dah durr” / “Ah hurr hurr hurr” captions on his Giraffatitan skull photos reminded me that there is a sauropod with a much, much stupider head than that of Giraffatitan . Step forward YPM 1910, a mounted skeleton that is the holotype of Camarasaurus (= “ Morosaurus “) lentus , in the dinosaur hall of the Yale Peabody Museum. Full details on this specimen next time!

Probably everyone who reads SV-POW! already knows that the manus, or forefoot, or sauropods was very distinctive.  The metacarpal bones, rather than being splayed out horizontally as in the forefeet of most animals, were arranged more or less vertically in a horseshoe shape, hence the characteristic shape of sauropod manus prints.
