61:2.2 Although the early [http://www.wikipedia.org/wiki/Eutheria placental mammals] sprang from [[carnivorous]] [[ancestors]], very soon herbivorous branches [[developed]], and, erelong, omnivorous mammalian families also sprang up. The [ [http://www.wikipedia.org/wiki/Angiosperms angiosperms] were the principal [[food]] of the rapidly increasing [[mammals]], the modern land flora, including the [[majority]] of present-day [[plants]] and [ [http://www.wikipedia.org/wiki/Trees trees], having appeared during earlier periods.

61:2.3 35,000,000 years ago marks the beginning of the age of [ [http://www.wikipedia.org/wiki/Eutheria placental-mammalian] world [[domination]]. The southern land bridge was extensive, reconnecting the then enormous  [http://www.wikipedia.org/wiki/Antarctica Antarctic continent] with [ [http://www.wikipedia.org/wiki/South_America South America], [ [http://www.wikipedia.org/wiki/South_Africa South Africa], and [ [http://www.wikipedia.org/wiki/Australia Australia]. In spite of the massing of [[land]] in high latitudes, the world [[climate]] remained [[relatively]] mild because of the enormous increase in the size of the [ [http://www.wikipedia.org/wiki/Tropics tropic seas], nor was the [[land]] elevated sufficiently to produce [ [http://www.wikipedia.org/wiki/Glaciers glaciers]. Extensive lava flows occurred in [ [http://www.wikipedia.org/wiki/Greenland Greenland] and [ [http://www.wikipedia.org/wiki/Iceland Iceland], some coal being deposited between these layers.

61:2.4 Marked [[changes]] were taking place in the fauna of the [[planet]]. The sea life was undergoing great [[modification]]; most of the present-day [[orders]] of [[marine]] life were in [[existence]], and [ [http://www.wikipedia.org/wiki/Foraminifers foraminifers] continued to play an important role. The [ [http://www.wikipedia.org/wiki/Insects insect] life was much like that of the previous era. The [http://en.wikipedia.org/wiki/Florissant_Fossil_Beds_National_Monument Florissant fossil beds of Colorado] belong to the later years of these far-distant times. Most of the living [http://en.wikipedia.org/wiki/Insects insect] [[families]] go back to this period, but many then in [[existence]] are now [[extinct]], though their [[fossils]] remain.

61:2.5 On [[land]] this was pre-eminently the age of mammalian renovation and expansion. Of the earlier and more [[primitive]] [[mammals]], over one hundred [[species]] were [[extinct]] before this period ended. Even the mammals of large size and small [[brain]] soon perished. [[Brains]] and [[agility]] had replaced [[armor]] and size in the [[progress]] of [[animal]] [[survival]]. And with the [[dinosaur]] [[family]] on the decline, the mammals slowly assumed [[domination]] of the [[earth]], speedily and completely destroying the remainder of their [[reptilian]] [[ancestors]].
