In this article. we define evolutoids and pedaloids of frontals on timelike surfaces in Minkowski 3-space. The evolutoids of frontals on timelike surfaces are not only the generalization of evolutoids of curves in the Minkowski plane but also the generalization of caustics in Minkowski 3-space. As an application of the singularity theory. https://www.shopwildwestes.shop/product-category/womens-outerwear-sherpa-trucker-jacket-cwj7356001/
