The tough, leathery shell that some mammals lay is characteristic of monotremes, such as the platypus and echidna. These mammals are unique in that they reproduce by laying eggs rather than giving live birth. The eggs have a protective, leathery shell, which helps safeguard the developing embryo in a terrestrial environment. This adaptation is a distinctive feature of these egg-laying mammals within the broader mammalian class.
Mammals don't lay eggs. The only mammal that lays eggs is a platypus, and they have leathery feeling eggs, but still a shell.
