Platecarpus model mesh, these models are sold as bare meshes, the included materials and textures were used in the model imagery rendering and are not intended to be sold, they are just a small bonus. Most models in the Prehistoric Denizens of the deep series are also rigged as a gift to buyers. Usually maps and textures upload automatically to its own folder, and they also show in your material tabs, but if in any case you are unable to find them, feel free to ask me and I will drop them to you, be sure your model is fully supported.
