Urantia During the Early Land-Life Era

60:0.1The era of ex­clu­sive ma­rine life has ended. Land el­e­va­tion, cool­ing crust and cool­ing oceans, sea re­stric­tion and con­se­quent deep­en­ing, to­gether with a great in­crease of land in north­ern lat­i­tudes, all con­spired greatly to change the world’s cli­mate in all re­gions far re­moved from the equa­to­rial zone.

60:0.2The clos­ing epochs of the pre­ced­ing era were in­deed the age of frogs, but these an­ces­tors of the land ver­te­brates were no longer dom­i­nant, hav­ing sur­vived in greatly re­duced num­bers. Very few types out­lived the rig­or­ous tri­als of the pre­ced­ing pe­riod of bi­o­logic tribu­la­tion. Even the spore-bear­ing plants were nearly ex­tinct.
