Spiked Carapace Texture

Hello.
I have been searching in Wc3 Veiwer in my hopes of finding the texture for the Spiked Carapace ability for the Crypt Lord.
According to the buff which uses the model, the path is:
Abilities\Spells\Undead\ThornyShield\ThornyShieldTargetChestLeft.mdl

However there is no texture named after that model.
I would appreciate any help regarding this.

it is part of the cryptlord texture(bottom left)

I should have suspected that.
Thanks.
