The evolution of a large powerful neck, jaws, and hind legs was determined to be a favorable adaptation. Smaller, yet powerful, forearms were part of that adaptation. When attacking another animal, T-Rex pivoted at the hip, like a lever at it's fulcrum. The massive and heavy head was counter-balanced below the hips by the legs and tail. Because the head and jaw muscles were so large, there was selective pressure to reduce the size of the arms in order to minimize the animal's weight above the hip.

no dinosaurs were reptiles and we are mammals.
The closes living relatives to all dinosaurs large and small are birds.

The smallest carnivorous dinosaurs, such as Compsagnathus, are insects and small vertebrates. Large carnivorous dinosaurs usually ate large and small herbivorous dinosaurs. Some, however, ate fish, including Spinosaurus and Baryonyx.
Mammals did not evolve until dinosaurs were prolific when they did appear they were very small and very scarce when dinosaurs died out.
no but you must be related to the dinosaurs because your brain is SMALL. no but you must be related to the dinosaurs because your brain is SMALL.
Birds evolved from small reptiles that lived during the age of dinosaurs, but not from the dinosaurs themselves.
Lesothosaurus, originally found in Lesotho Africa.
Not all dinosaurs had large feet. Some dinosaurs were small and didn't have big feet.
Small mammals or herbivorous dinosaurs
