Articles on Dilong and "a hobbit" in the 21. Century magazine
my new issue of the 21. Century magazine (Czech: 21. stoleti) has a nice
articles on both important fossil discoveries of the last year. I'd like to ask
a few questions on both topics. As for Homo floresiensis:
1.) what is the general meaning of it, could it be a dwarf (insular) form of
late H. erectus?
2.) With the braincase volume of only 380 ccm, this dwarf man was less
inteligent than H. erectus or even Austrolopithecs. Of course the size of a
brain is not equal to its abilities, but still...how could it created float to
get to the island, when even H. erectus with the braincase volume around
700-1250 ccm was unable of such thing (AFAWK). Also, how could they know and
use fire with "Australopitecus' brain"? Did they learn how to handle it from H.
3.) There's a mention of two species of giant monitors living in the same area
as hobbits. Our old well known comodo dragons but also some type of larger
reptile. Does anyone know more about this second monitor of flores? And was it
possibly preying on hobbits?
4.) Hobbits were living in a long span of about 20 thousand years there. But
when did they dissapear? 12 or 11 thousand years ago? Or possibly much later?
And again cryptozoology: may the existence of "Orang pendek", "Nguoi rung",
"Batutut" and other dwarf forest men be true? Or in other words: how big is a
chance, that H. floresiensis survived in a remote, hardly penetratable forest
areas to this day?
As for Dilong paradoxus:
1.) Is dilong thefinal proof for asiatic origin of tyrannosaurids?
2.) Is feathery integument a synapomorphy for a whole tyrannosauroid clade?
3.) Did featery integument probably appear only in juvenile stages while in
adults it was secondarily lost?
4.) What where the climatic conditions (weather, humidity) in Liaoning about
130 Ma ago?
5.) Is this genus earlier than Eotyrannus from the Island of Wight? And is it
6.) Is there anything new on the "C-rex" specimen, said to be 10% larger than
Sue (rex, not scientist)?
7.) Is validity of _Tarbosaurus efremovi_, _Gorgosaurus lancinator_,
_Gorgosaurus novojilovi_, _Jengkhizkhan bataar_ and _Maleevosaurus novojilovi_
once assigned to a single species _Tarbosaurus bataar_ now generally agreed?
And how are they distinguished?
8.) In which parts of a tyrannosaurian body was the feather concentrated most?
Which parts were probably holow?
9.) Does this find change somehow our understanding of a thermoregulatory
mechanics in large tyrannosaurids (gigantothermy)?
Thank you, in advance. Vlad "Arrhinoceratops" Socha
P.S. I was invited for the next week's opening of an interesting exhibit "Life
in primeval seas and oceans" with illustrations of a compatriot painter Jan
Sovak. Of course, there will also be paintings of dinosaurs as todays
paleontology is "nothing" without them °o)
