Articles on Dilong and "a hobbit" in the 21. Century magazine

Good day,
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. 
sapiens perhaps?
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 
more basal?
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)
