Hello!
I long to know some plesiomorphies of various
theropod clades. There are databases in the net, but I've found it somewhat
difficult to extract information from them. I don't need all of the
plesiomorphies, only some of the most important ones. In the following, I will
be using the nomenclature the way Sereno does in his 1999 paper "Dinosaur
evolution".
Theropoda
I think these were functionally tridactyl. Anything else worth noticing? Neotheropoda I don't know. Tetanurae
I recall they had only three fingers (per hand). Other things? Neotetanurae Well? Coelurosauria I haven't got the faintest idea. Maniraptora These had semilunate carpals. But that's not all, is it? Paraves
I don't know! Aves Please tell me! Thanks in advance, Henri Rönkkö PS. This is
important.
