The smallest dinosaur still remains as-well, we can't find out! Microraptor, so far, is the smalest, but Comsagnathus was a pretty petite one as well.
Epidexipteryx is the smallest known dinosaur. It was a feathered theropod less than 10 inches long and weighing about 0.36 lb.
The smallest Spinosaur yet discovered was called Irritator.
No.There is actually a debate over which is the smallest dinosaur, because fossilisation and weathering can cause shrunken features and missing details.The top 5 argued smallest dinosaurs are:Ohmdenosaurus- 4 m (13 ft)Blikanasaurus- 5 m (16 ft)Magyarosaurus - (17 ft)Europasaurus - 6 m (20 ft)Vulcanodon - 6.5 m (21 ft)Also, bear in mind that not every dinosaur has yet been discovered.
No. There are others that have been discovered that are smaller and there could be others that have to be discovered yet.
It is a new species that has not yet been named.
Probably billions, most of which haven't even been discovered yet.
"Last"? The most recent discovery: Just a few weeks ago another was discovered in Spain (beginning of August 2009). The youngest dinosaur (if that is what you mean by "last") hasn't been discovered yet because the thousands of species of birds living today could be classified as dinosaurs!
That depends where you are in space. If you are near Earth, maybe Pluto. If you are near Pluto, maybe Mercury.
As far as we know, it's Mercury. If there's a closer planet, it hasn't been discovered yet.
No, a full DNA strand has yet to be extracted from dinosaur remains
We don't know they haven't been discovered yet
An asteroid is a rocky object in space. It may be a broken part of a planet. The smallest observed asteroids are 10 meters in size . There may be many asteroids smaller than this but they can not be detected yet and also have not been observed yet.
