Alright I will describe how I imagine the textures look like:

• I imagine it have a kinda sculpted look. Like someone sculpted it from clay with tools.

• It's skin is a mix between human skin(Original texture) and fungus.

• It's skin doesn't look too dinosaury but is still some what ruff.

Sorry if I am a little too specific. Please be mindful that I am a beginner with Blender and don't know how to use certain things. Can someone help find me a texture that somewhat looks like this? When this model is finally done I will probably make a found footage video of it and will release it.
