Re: Eodromaeus, new basal theropod from Triassic in Argentina



Anyone else confused with the phylogenetic definitions employed by Martinez, 
Sereno and others on p 210? The extract in question is copied below with square 
brackets being my notes:

"9. Higher taxa cited in the text are defined as follows (www.taxonsearch.org): 
[1] Dinosauria, the least inclusive clade containing Tyrannosaurus rex Osborn 
1905 and Passer domesticus (Linnaeus 1758); [2] Ornithischia, the most 
inclusive 
clade containing Tyrannosaurus rex Osborn 1905 but not Ornithomimus 
edmontonicus 
Sternberg 1933, Troodon formosus Leidy 1856, Velociraptor mongoliensis Osborn 
1924; [3] Saurischia, the least inclusive clade containing Tyrannosaurus rex 
Osborn 1905 and Gorgosaurus libratus Lambe 1914, Albertosaurus sarcophagus 
Osborn 1905;"


[1] appears to be Tyrannoraptora
[2] looks like Tyrannosauroidea
[3] is Tyrannosauridae
