How about the Chuul, weighing in at 11HD and Str 20, Dex 16, Con 18, Int 10, Wis 14, Cha 5? I might tone that down a little for a 7HD critter, but it might work.

I'm fine with those physical stats.

The Santa-Claws is a lot bigger & stockier than a Phase Spider (Str 17, Dex 17, Con 16), so ought to have a higher Str and Con, although that Dex seems way too good.

Maybe not quite that high a Strength, either.

Wisdom 10, Cha 3?

Str 19, Dex 13, Con 18, Int --, Wis 10, Cha 2 ?

Do anything with this?

It lives in one of two types of caves: those that are narrow tunnels, and those with narrow entrance tunnels but chambers wide enough for the animal to turn around in. It always backs into the former cave. Either way, anyone attempting to invade its lair will face its formidable jaws and head, which is more heavily armored than the body.

While 3.5 doesn't allow rules for different ACs for different body parts, I could see giving it a circumstance bonus to AC when fighting in tunnels no larger than its Space. Thoughts?

Sure, why not.

A +3 bonus like the difference in the original's head & body ACs?

Something like this?

Armored Head (Ex): A sanctacaris gains a +3 circumstance bonus to its Armor Class when fighting in tunnels no larger than its Space.

All works for me.

That looks fine.

They don't have anything special going for them, so CR would be pretty low.

Advancement: 8-11 HD (Large); 12-21 HD (Huge) ?

A sanctacaris is 15 feet long and weighs x pounds.

They're build pretty much the same as a Leanchoilia, so ought to weigh 4000-8000 pounds. Let's say 4000, the cusp of Large/Huge.

A sanctacaris is 15 feet long and weighs 4000 pounds or more. ?
