Like fellow member HP Dinorampage, I've got some questions to and I hope if someone can help me out with the following:
1) Ginnareemimus is reported to have an almost "arctometatarsalian" pes, like in Sinovenator, but how does
this relate in terms of their relationships, are they closely related or does this mean the arctometatarsalian
pes can be achieved by convergence leaving it as practicly meaningless in phyletics?
2) Another Ornithomimid question: after looking at some figures of the redescription of Archaeornithomimus in
a JVP-issue (can't remember the volume anymore) and reconstructing it's pelvic girdle + hindlimbs,
something came up along the way which was also quite suspect in the figures: the pubis, at least it's distal
end is somewhat recurved, giving the impression of an opisthopubic state of the pelvis. Is this another clue
of the Ornithomimids being related to an Archaeopteryx or an animal close to this?
3) Again on Archaeornithomimus and the supposed synonymy to Garudamimus, what are the shared
characteristics between the two apart from shape of the pubis and are there any differences between
them? The femur for instance is practicly straight in A. while it is curved in G. and the crest on the tibia
(damn' names...) on it's proximal end is less pronounced in A. compared to G., but there are more right?
4) Is Confuciusornis dui still considered a valid species of Confuciusornis?
5) If so, what is it supposed lifestyle with the upward curving horny sheat at the tip of the beak? It is somewhat
similair in structure to the beak in Rhamphorhynchus for example, which probably pierced it's prey (most of
the time fish) while skimming the waters. Is this practice reasonable and is it appliable to C. dui? And what
are the supposed life-style for the other Confuciusornithes Confuciusornis, Longchengornis and
6) Changchengornis is smaller than Confuciusornis by almost a third IIRC and in extant mammals, the predator
is smaller than it's prey (some examples can be thought of such as the great white shark), does this
indirectly mean that Changchengornis was more predatorial based the other Confuciornithes? The hooked
beak can be seen as another clue for it's predatorial lifestyle, but apart from that.
7) Is a vulcanic eruption the cause of the major faunal death in the Lianoning basin or are there other theories
8) Does someone please send me scans of the skeletal material in the 2002 JVP publication of
9) In DA HP Greg Paul states that Eoenanthiornis could be a juvenile or subadult genus, is this correct?
Thanks in advance for any help!
