Hello folks-- Does anyone have a good way of distinguishing between ornithomimid and tyrannosaurid metatarsals (II-IV)? Other than size? A little easier: OK, how about between arctomet and non-arctomet (e.g. dromaeosaur, oviraptorid) MTs II-IV? Any quick-and-dirty hints from the experts would be just plain swell. --John R. Hutchinson
