So, I'm preparing to take in another rescue bearded dragon. Adult male, around 3 years of age, snout-vent length around 9-10 inches.

This male was housed happily with a younger smaller male for over a year. One day, something changed... the one I'm taking in bit off two legs of the younger guy. The little guy took off several toes and the end of the tail of the big one. The owners decided to euthanize the little beardie. I am NOT planning on housing this guy with Mr. Gimpy, my male beardie. He's not very tame at all.
The beardie I'm taking in has a good chunk of tail missing. The current owners say "well it looks like his tail is starting to grow back, now"... but I have no reason to believe that bearded dragons regenerate their tails. I've seen the dragon and inspected him... the end of the tail is quite dark and looks somewhat blackened. I'm thinking necrotic tail tissue is what I'm seeing, and it may require another surgery to remove the dead part and get back to a healthy tissue state.
Looks like he's lost other toe tips due to bad sheds. The current owners think those were always gone, "birth defect" she says. I doubt that.

Anyone have any evidence that beardies have any tail regeneration capabilities? I can't find anything online to support that theory.

Now I've got to go move furniture and set up my other 55 gallon terrarium for this newcomer... which sucks as I have a second 55 gallon on top of that one (using it as a stand). You know you've got too many damn cages lying around when you have to resort to using them as tank stands.

Hopefully I'll be able to get some pictures of this guy... my housemate has a digital camera. I'm convinced our camera is totally dead now.

When the tip of my beardie's tail went dead and dropped off after being bitten by a young iguana there was no sign of regrowth whatsoever

I imagine that tail regeneration is a trait of those animals that can throw their tails at need. He will most likely do just like a green iguana. If the tail is damaged, I would watch for dry rot just like in an iguana, also.

My understanding is that lizards that do regenerate their tails (and not all do, I have no idea if breadies do) will only do so if the tail breaks at one of the "fracture planes" where the tail is designed to break. If they drop their tail, it will grow back. If you chop it off, it will not. I am not an expert on this, though, so if anyone wants to correct me ...

Ok, correction it is. A leopard gecko can regenerate their tail. If the tip is damaged, they may grow a second tail tip for the injury site. One of my leo girls had the tip of her tail bit off. It grew back from the site of the bite, or actually, a small piece became necrotic and I removed the dead flesh and it grew from about 1/4 inch from the bite where the flesh was live. I have posted the links to photos of it at one time.
On the other hand, have you heard of say a green iguana regrowing a tail?

Regenerative properties are in some retiles and amphibians, not all. And not in equal amounts, either, as it were.

Yes, when one of my igs dropped his tail it started to regrow, then during the regrowth he dropped it again and it started to regrow yet again

My first iguana regrew his tail, and it came back black. The one I have now lost part of her tail after damaging it whipping at me, and it hasn't regrown.

Melissa Kaplan's Wally lost his tail after a car door was slammed on it and it never regrew
neither has any of mine even after many years
