flesh out
The New York Timesにあった記事の見出しを採り上げます。
flesh outは「…に肉をつける」（『プログレッシブ英和中辞典』小学館）という意味で，見出しのFleshing out the Bonesは文字通りに捉えれば「骨に肉付けをして（恐竜を）再現する」という意味となります。
しかしflesh outにはこの他に「〈構想などを〉（…で）具体化する」（『プログレッシブ英和中辞典』同上）という意味があり，記事の後半にもWhere theory becomes reality.とあることから，今回の見出しは「理論を具体化する」という意味を含んでいると考えられます。（Koyamamoto）
Fleshing Out the Bones
Behind the Scenes at ‘Pterosaurs: Flight in the Age of Dinosaurs’
In a brightly lit production studio at the American Museum of Natural History in February, 12 artists were hard at work, heads down, eyes focused.
In one corner, a sculptor was shaping clay to create a cat-size flying reptile, a rhamphorhynchus, using a tracing of the animal’s footprints that had been captured in a stone trackway excavated in Utah. In a back room, in hazmat suits and respirators, a team of three was building another kind of a pterosaur, as the flying reptiles are known: a nine-foot-long tropeognathus from foam, fiberglass and epoxy around an aluminum frame.
... These three floors in this part of the museum complex — the Power House, where the coal fires were once stoked to heat the entire museum — are where art meets science. Where theory becomes reality.
