Moving on to living species, but staying in the theropods, we come to the subject of our second installment, a (supposed) raven skeleton, available for $7.99 at Party City (and elsewhere).
Noticeably weird is the fact that the ribcage is completely open in front, with no sternum to connect the ribs.
But, even more weirdly, whoever designed this skeleton seems to have been under the impression that birds have bones in their feathers. In the areas corresponding to the flight feathers of the wings and tail, there are elongate rows of bones similar in appearance to the fingers that support a bat’s membranous wings. (Birds do have remnant finger bones in their wings, but they very small and do not parallel the flight feathers.)
