A quote from Walking on Eggs: "...coelurosaurs were
feathered; even the colossal Tyrannosaurus must have had a feathered
body at some early stage of its life. However, scientists do not believe that
adult tyrannosaurs were feathered because the combination of this insulating
covering and their large size might have posed a disadvantage in regulating the
animal's body temperature."
OK, can anyone tell me what this belief is based
on? Is there sound scientific evidence for it, or is it conjecture?
Thanks to anyone who can help!
