Question
Chapter 19.2, Problem 2CC
Summary Introduction
To determine:
The resemblance of fossil of an extinct mammal that lived in the Andes with present day mammals that live in South American jungles or present day mammals that live high in Asian mountains.
Introduction:
Gondwana was a supercontinent about 250 million years ago and this continent contained subcontinents: South America, Africa, Antarctica, Australia, the Arabian Peninsula and Indian subcontinent.
The Asian and South American continents were slowly split apart 65 million years ago during the age of the dinosaurs and the continents of Africa and South America drift apart 120 million years ago.

WHAT IF? If you discovered a fossil of an extinct mammal that lived high in the Andes, would you predict thatit would more closely resemble present-day mammalsfrom South American jungles or present-day mammalsthat live high in Asian mountains? Explain.
MAKE CONNECTIONS Develop a hypothesis to explainwhy the diversity of mammals increased in the Cenozoic.Your explanation should consider mammalian adaptations as well as factors such as mass extinctions andcontinental drift (review Concept 25.4).
WhAt IF? Your measurements indicate that a fossilizedskull you unearthed has a carbon-14/carbon-12 ratio about1⁄16 that of the skulls of present-day animals. What is theapproximate age of the fossilized skull?
