My opinions about T.rex

The most famous predatory dinosaur his name,Tyrannosaurus rex. 


There are many things we know about T.rex about their behaviour,environment etc,but the hunting behavior is poorly known but in my opinion it just acts like a modern day African Lion,and I think they also hunted in family groups from 4-10 individuals or as many as 15!!I 


Think like a Lion they can run in short bursts of speed because of its bulk and massiveness,and in my opinion T.rex is an ambush predator.


T.rex can kill a prey in just a matter of seconds or minutes(depending on the prey) with its sheer bulk,teeth and bite force!


Therefore,making the T.rex the KING of all Dinosaurs!




NOTE:These are all speculations and opinions.

Was Archaeopteryx a flyer or glider?

Archaeopteryx lithographica is the most primitive bird known. 


Archaeopteryx means "Ancient Wing".

There are still debates whether Archaeopteryx is a glider or capable of powered flight.


As in the wings of modern birds, the flight feathers of Archaeopteryx were somewhat asymmetrical and the tail feathers were rather broad. 


This implies that the wings and tail were used for lift generation. 


However, it is unclear whether Archaeopteryx was simply a glider or capable of flapping flight. 


The lack of a bony breastbone suggests that Archaeopteryx was not a very strong flier, but flight muscles might have attached to the thick, boomerang-shaped wishbone, the platelike coracoids, or perhaps to a cartilaginous sternum. 


The sideways orientation of the glenoid (shoulder) joint between scapula, coracoid and humerus—instead of the dorsally angled arrangement found in modern birds—suggests that Archaeopteryx was unable to lift its wings above its back, a requirement for the upstroke found in modern flapping flight. 


Thus, it seems likely that Archaeopteryx was indeed unable to use flapping flight as modern birds do, but it may well have utilized a downstroke-only flap-assisted gliding technique. 


There are some Archaeopteryx fossils found in water areas,thus there are some theorys that Archaeopteryx uses its wing to walk in the water just like the Basilisk does.
