Holtz et al. (2004) suggested it would be a basal tyrannosauroid, but my unpublished large Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-62570477231205725422010-02-19T21:02:39.600+01:002010-02-19T21:02:39.600+01:00Did anyone ever publish that Santanaraptor is tyra...Did anyone ever publish that Santanaraptor is tyrannosauroid?<br />Tugulusaurus seems to be very basal coelurosaur (Rauhut & Xu, 2005; Smith et al., 2007).<br />I think that neovenatorids could be albo slightly closer to birds than allosauroids (=they are, by definition, cuelurosaurs). I think that Benson et al. didn't test this possibility, as they only include 3 colurosaurs (Matthewhttp://www.dinozaury.comnoreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-45395615630482907192010-02-19T20:54:56.899+01:002010-02-19T20:54:56.899+01:00Wait, so compsognathids are paraphyletic?Wait, so compsognathids are paraphyletic?Zachhttps://www.blogger.com/profile/08692080707969333711noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-68624001867648546412010-02-19T18:13:09.850+01:002010-02-19T18:13:09.850+01:00Is it a compsognathid?

If tyrannosauroids were present in Middle Jurassic Europe, it seems plausible that they reached a Pangean distribution around the end of Jurassic, begetting some Gondwanan (at least Northern Gondwanan) João Simõeshttps://www.blogger.com/profile/10222169018695033058noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-62926168931811400162010-02-19T15:20:52.817+01:002010-02-19T15:20:52.817+01:00Mai avuto pregiudizi in tal senso.

Certo che uno scontro tra Achillobator e Tarbosaurus sarebbe stato forse più 'spettacolare'.Hulkolagushttps://www.blogger.com/profile/15012423218278690859noreply@blogger.com
