Is it likely for Kentrosaurus to have the bone ossicles known from Stegosaurus?

What are the largest dinosaurs for Asia and Europe? And I'm talking about from enough material to warrant a genus and nothing like Bruhathkayosaurus

For Asia: Got options here. Mamenchisaurus sinocanadorum had an 18m neck alone and an upper body length estimate of 35m. "Huanghetitan" ruyangensis is notable for having the deepest body cavity of any known dinosaur. Ruyangosaurus and Daxiatitan are also giants comparable to the biggest of those found in Argentina.

For Europe: Turiasaurus is by far and away the largest dinosaur in Europe. "Angloposeidon" might be a comparably sized relative of Sauroposeidon, but it's still yet to be given a formalised genus, species, or clade. It's just some cervicals that exist in literature and photographs. Go with Turiasaurus on this one. It's comparable to Argentinian titanosaurs as well, but is yet somehow completely unrelated.

I read something recently about Turiasaurus being downsized (from 26 meters in lenght and 50 metric tonnes to 22 meters and 30 metric tones).

I think the reason given is that the original estimate was based on the diamater of the humerus being compared with the ratio in Brachiosaurini sauropods which had a thinner if longer humerus than "Turiasauria".

I heard the downsize was from 37m to 30m for Turiasaurus...

How would Tenontosaurus move ?
Was it an obligate quadrupedal or could it also move on two legs if needed ?

It was actually a full biped, recent studies confirm.

If I find that paper again, I'll forward it to ya.

Where is the southernmost location fossils of Tyrannosaurus and Triceratops were found?

Well wherever you find T-Rex you'll find triceratops and vice versa but after a quick look on Wikipedia it would appear the southernmost range for T-Rex is Texas and New Mexico whilst Triceratops's is Colorado but the last part I might be wrong
EDIT: Yes it would appear Trike's farthest range was Colorado and as you went further south it's more likely you'd see Torosaurus perhaps Triceratops out competed them in the north whilst they continued to thrive in places like Texas

Fossil beds in Texas tend to be slightly older than in Hell Creek.

It's also possible that southern Tyrannosaur remains might belong to the undescribed genus "Alamotyrannus brinkmani"

Giant Crocodilians like Deinosuchus and Sarcosuchus sound wise how similar would they have sounded to modern crocodilians and for the sake of curiosity could they "roar"

And also footsteps, in Giants like Apatosaurus or Brachiosaurus how loud would their footsteps have been and could they be heard from a short distance (like 100 yards or more(

Sarcosuchus is hard to say, but Deinosuchus probably sounded like modern Alligators do (which is to say it sounded very diverse). Neither was capable of roaring, only very specific mammals can roar.

If I can hear a neighbor closing their garbage can lid from further than that than probably one could hear their footsteps from 100 meters or so, at least in the right conditions.
