Re: Diminutive dinosaurs

> As far as I know the smallest adult dinosaur remains

*Mellisuga helenae* aka *Calypte helenae*, a hummingbird from Cuba and Isla
de Pinos, which weighs 2 g and is 9 cm long, of which 1.25 are made up by
the beak and 6.5 by the tail. Eats twice its body weight per day.

Oh, you mean the smallest nonavian one? :-) *Microraptor zhaoianus* -- 48
cm, smaller than *Archaeopteryx*.

1.4 m long when adult (which the "60 cm" specimen from Germany isn't).

"Etc." being mammals and... birds, means, dinosaurs. :-)
