Our Horned Mountain Dragon

Question
QUESTION: Hello, my name is Kalista and I'm only twelve but we have been kind of wondrous today.
Our lizard who is now named Medusa has layed about fifteen eggs today. We got her about a year ago and we have no mate for her. The pet store that we got her from didn't have a mate in the tank either. I was wondering if you could tell me how this is possible of her laying the eggs?

ANSWER: Reptiles, like birds, can lay infertile eggs.  However, that is a pretty large clutch for infertile eggs.  It's possible that she was with a male before you got her (she came from somewhere, before the pet store), and retained sperm.  Many reptiles can do this, and doing so for as long as a year (or even longer) is not unheard of.  

If you get the eggs into a proper incubator quickly, it's certainly worth a try to hatch them!  You'll know within a week or so if they are infertile.  They will sink and discolor, and then begin to smell.  If they stay white and plump, then they're fertile!

Here are instructions on incubating them:  http://www.kingsnake.com/mhd/MHDkingsnake.html#incubate

You have quite a wait ahead of you, if they're fertile!

Either way, increase your dragon's calcium intake, and make sure her UVB light is current (bulbs should be replaced every 6 months).  Laying eggs takes a lot of bodily resources.

QUESTION: She buried most of the eggs so we cant see them but the ones that we can see shriveled up and my dad told me they would all be duds and that hes going to take them out and put them in the dumpster outside.  Should he do this?

Answer
Well, if they don't have proper humidity, they will shrivel--if they get too dehydrated, they will die.  If you want to save them, you'll have to dig them up and put them in a proper incubator.

If they shrivel after they're in a proper environment they they are either infertile, or have died.

Perhaps he doesn't feel he can afford an incubator.  If so, then it's probably best to just throw them out--they will not survive without proper humidity and temperatures, even if they are fertile.
