75 mya we shared a common ancestor with Glires which include rodents (mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, hamsters, and capybaras) and lagomorphs (rabbits, hares and pika)
85 mya we shared a common ancestry with this large group of placental mammals that evolved in the northern supercontinent of Laurasia which includes shrews, hedgehogs, pangolins, bats, whales, most hoofed mammals, and carnivorans, among others.
105 mya, in the mid Cretaceous period, we shared a common ancestry with the placental mammals: elephants, elephant shrews, dugongs, manatees,hyraxes, aardvarks, etc. They all hail from Africa, as hinted by the name of their clade, Afrotheria
140 mya, during the early Cretaceous period, we shared a common ancestry with Kangaroos, wallabies, sugar gliders, opposums and marsupial moles. Most of these pouched animals survived in Australia where they filled most of the ecological niches occupied by mammals in the rest of the world after the extinction of the dinosaurs.
Around 230 mya during the Triassic period, dinosaurs evolved and flourished to occupy all the ecological niches including the air, mastering flight which until then had been the domain of the arthropod insects.
530 mya we shared a common ancestry with these craniates which lacked a spinal column but did have a rudimentary notochord which transmitted innervation to their elongated bodies. Trilobites come from this period when there was an explosion of hard bodied life that fossilized well to leave us evidence.
