In Pursuit of Early Mammals (Life of the Past)

By Zofia Kielan-Jaworowska

In Pursuit of Early Mammals offers the heritage of the mammals that lived through the Mesozoic period, the time while dinosaurs governed the Earth, and describes their origins, anatomy, systematics, paleobiology, and distribution. It additionally tells the tale of the writer, a world-renowned expert on those animals, and the opposite admired paleontologists who've studied them. Zofia Kielan-Jaworowska was once the 1st girl to guide large-scale paleontological expeditions, together with 8 to the Gobi barren region in Mongolia, which introduced again vital collections of dinosaur, early mammal, and different fossils. She stocks the problems and pleasures encountered find infrequent fossils and describes the altering perspectives on early mammals made attainable by means of those discoveries.
