On display in Copenhagen, Denmark's Ny Carlsberg Glyptotek art museum is this glass display case filled with noses of myriad shapes and sizes. Why?
According to curator Anne Marie Nielsen, noses on 19th century statues are notoriously fragile and would frequently break off. So the owners of the statues (or perhaps even prior museum curators) would replace them with marble or plaster replicas. Nowadays though, the museum removes any replacement noses because they only want to display the original sculptures, faults and all.
“About 20 years ago, the museum had a box filled with noses [in our archives], and we weren’t sure what to do with them,” Nielsen tells Smithsonian.com. “We decided to group them together and put them [on display].”

Imagine an apatosaurus with a long, elephant-like snout. Plenty of people have. That's because the nostril placement on sauropod dinosaurs is, in some ways, remarkably similar to that of trunked animals that live today. In both cases, the nostrils are large, and they're located up around what we'd call the forehead, kind of smack between the eyes.
On the one hand, this is one of those things that it's really hard to ever know for certain. We don't have preserved soft tissue, so when we make models of what dinosaurs might have looked like we're really going on clues from the bones and comparisons to living animals with similar bone structure. Because of that, it is somewhat reasonable to suggest that hey, maybe, sauropods really did look like grumpy diplodocus in the image above. It's fun to speculate.
But not all speculations are created equal. In a fascinating post at the Tetrapod Zoology blog, Darren Naish explains why a superficial similarity to trunked animals isn't enough to counteract the much-more prevalent evidence against sauropod trunks. One of the more interesting lines of evidence he points out is the fact that dinosaurs apparently lacked the facial which form the trunk in living animals. We know this partly because muscles leave their signature on bone, and Naish says there's no evidence sauropods had the right facial muscles. It's further bolstered by the fact that the animals most closely related to sauropods don't have those facial muscles, either.
Naish's piece reminds me of the last time we talked about sauropod biology here. Read the rest “Sauropods might have had trunks, but probably didn't”
