Coracoid question

Dave Peters asked me to pass this along to the list...

Gotta know the answer to the following:

1. When did crocodilians get that strut-like coracoid and what's the
story (hypothesis) behind it?

2. Can you think of any other genera in which the manus digits increase
laterally until digit V, which grows no longer than metacarpal IV. I can
think only of Tanystropheids, Cosesaurus, Longisquama and of course,
