Classicly

A waste of waters heaved sullenly beneath a dismal canopy. Thin, slimy masses floated here and there about the shallows of a little cove or clung to its sodden beach. The warm waters teemed with the myriads of life. Strange creatures swarmed the seas devouringly or nosed and hunted along the shores, and others of other forms ranged and floundered and fought in the depths and glades of the gigantic fernlike forests. It was a time of heat and moisture and of fierce development, terrible, vast, imposing.
