Yes, and no. Yes, because all the BIG dinosaurs that were preadators (or prey) did have tails. And no, because bugs were living back then, right? Bugs don't have tails, and they lived in the dinosaur time. (and are still here today)
In nature - yes. There are domesticated birds that are tail-less - usually called rump-less for instance Araucana chickens.
Probably. We haven't yet found all the possible dinosaurs, but those which have been discovered were all tailed creatures.
No, not all lemurs have tails. The indri, the largest of the living lemurs, lacks a tail. Also, some extinct giant lemurs (which died out around 500 years ago) also lacked a tail.
Yes all lizards have tails
No because some swam in the sea!

Mice should not loose their tails. If they do, than an animal harmed it or the tail got stuck. Mice do not drop their tails like lizards, and mice are mamals, all mamals do not loose their tails
Yes
they grow back because lizards reproduce asexually
Toads live in the forest. Lizards live in the desert. Lizards have tails toads do not.
All lizards can lose their tails by getting it eaten off or something, but some lizards can 'lose' their tails. As in, if you frighten it or catch it by the tail, the lizard could detatch the tail from their body (and it would still move to confuse the attacker), and they could run away and regenerate the tail. =) -kelsey.
