Default What A Pyramided Tortoises Shell Looks Like Vs. A Nonpyramided Tortoises Shell

These are 2 California Desert tortoises, but pyramiding is the same for every tortoise.
The Pyramided Tortoise First.

The pyramided vertebral scutes and whats underneath, notice that the sutures between the bones are not very tight

Everything I've read about pyramiding is that it isn't physically bad for the tortoise. I think the proof is there that in fact it is bad for them.

Thank you for these! Very interesting!

Dan, would you say that pyramiding is caused by low-quality diet or for other reasons? I have always wanted to know this...

I found an interesting article about pyramiding on this site.http://www.ivorytortoise.com/informa...tortoises.html. According to this diet has little to do with it. Humidity of all things. Check it out.

Thank you! I will read it now.

I have read many things about Pyramiding but there are too many different opinions, I am not sure what to believe!

I'm not getting how humidity can prevent or cause pyramiding. Those studies always perplexed me.
If you look at the pictures it's the bones that pyramid, not the scutes. Humidity only helps the scute material from sticking together at the edges and causing lopsided growth of the scutes, but not affecting the bone underneath.
Bones need 4 things to grow, calcium, phosphorus, vitamin D3 and enough calories to untilize the first 3. From what I've always seen it's a deficiency or lack of 1, 2, 3 or all 4 that causes pyramiding.

Glad I could help by posting these pictures

Danny

I never got how humidity could be linked but a few breeders have said how much smoother their hatchlings shell had grown when given the option of a humid hide, so thats what mine are getting. Cant hurt after all...
