The UB speaks in paper 61 about an early egg-laying mammal, the current scientific discoveries agree that the first mammals were indeed an egg-laying species.

61:1.9 (694.1)
45,000,000 years ago the continental backbones were elevated in association with a very general sinking of the coast lines.
Mammalian life was evolving rapidly. A small reptilian, egg-laying type of mammal flourished, and the ancestors of the later kangaroos roamed Australia.
Soon there were small horses, fleet-footed rhinoceroses, tapirs with proboscises, primitive pigs, squirrels, lemurs, opossums, and several tribes of monkeylike animals.
They were all small, primitive, and best suited to living among the forests of the mountain regions.
A large ostrichlike land bird developed to a height of ten feet and laid an egg nine by thirteen inches.
These were the ancestors of the later gigantic passenger birds that were so highly intelligent, and that onetime transported human beings through the air.

Early synapsids* laid eggs with parchment-like shells intolerant of desiccation and apparently dependent on glandular skin secretions for moisture.
Mammary glands probably evolved from apocrine-like glands that combined multiple modes of secretion and developed in association with hair follicles.

*Synapsids are a group of animals that includes mammals and every animal more closely related to mammals than to the other members of the amniote clade, such as reptiles and birds.
