Even Minmi as close to ankylosaurids instead of nodosaurids seems to be a good start for new findings at Australia, maybe you will find entirely new clades there.João Simõeshttps://www.blogger.com/profile/10222169018695033058noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-22606084567474013282010-05-24T08:33:23.539+02:002010-05-24T08:33:23.539+02:00The two specimens are a bit different.

It belonges to an indeterminate non-therizinosaurid, non-oviraptorosaur, non-pygostylian theropod.<br />The holotype of Kemkemia shows at least one autapomorphy and also an Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-44485162711181337622010-05-24T00:19:54.170+02:002010-05-24T00:19:54.170+02:00Andrea, aside from its position in the series, Wal...Andrea, aside from its position in the series, Walgettosuchus shares one thing with Kemkemi: They are both distal caudals used to support nomenclature. Would you as easily support the identity for Walgettosuchus as for Kemkemia. The lformer was originally treated as a crocodilian caudal, before being referred to Theropoda, but it's been regarded as an indeterminate theropod by every paper Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-9672680471880726982010-05-23T16:44:51.297+02:002010-05-23T16:44:51.297+02:00The New Zealand dinosaurs are isolated and fragmem...The New Zealand dinosaurs are isolated and fragmemtary remains from the Campanian-Maastrichtian: a mid-sized ornithopod ilium and several theropod fragments (most phalanges).Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-75688787496967049142010-05-23T16:23:14.220+02:002010-05-23T16:23:14.220+02:00How about the New Zealand dinosaurs?How about the New Zealand dinosaurs?João Simõeshttps://www.blogger.com/profile/10222169018695033058noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-7441166195968658752010-05-23T14:24:37.233+02:002010-05-23T14:24:37.233+02:00Walgettosuchus seems a very distal caudal, based o...Walgettosuchus seems a very distal caudal, based on joined pre- and postzygapophyes, narrow neural arch and neural spine absent.<br /><br />Reduction of the neural arch width, absence of a robust neural spine and apparent presence of relatively robust prezygapophyseal base are symplesiomorphic for theropod distal caudals: I see no evidence for a relationship with Kemkemia (or any other theropod Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-42237136092085128322010-05-23T13:55:18.632+02:002010-05-23T13:55:18.632+02:00A lot of Agnolin et al is basically super-taxonomi...A lot of Agnolin et al is basically super-taxonomic assignment: Dromaeosauridae, etc. In some cases, they miss precise opportunities to perform more daring statements:<br /><br />Qantassaurus, Atlascopcosaurus etc may actually forma gradational relationship, if not a clade, with the SA "gasparinisaurs." I will certainly be alluding to this in my take on the subject.<br /><br />Agnolin Anonymousnoreply@blogger.com
