"In Egypt, however, the serpent was the symbol for duality or, more accurately, for the power that results in duality.  And that power is itself dual in aspect; it is simultaneously creative and destructive: creative in the sense that multiplicity is created out of unity, destructive in the sense that creation represents the rupture of the perfection of the Absolute....." (J.A. West, 1993).

Angiosperm Evolution

Did Angiosperms First Appear in the Early Cretaceous?

Paleobotany and Palynology

Fossil Evidence for a Parasitic Angiosperm
in the Late Triassic

The Controversy and Darwin's Abominable Mystery

Early Dicot Stem Anatomy and Leaf Morphology

Lily-like Pollen in the Upper Jurassic Type Section

Sanchesia-like Pollen (Acanthaceae) in the Late Jurassic

Diverse Angiosperm-like Pollen in the Late Triassic

Half Monocot - Half Dicot in the Late Triassic

Dicot-like Leaf from the Late Triassic

A new Triassic Gnetophyte - Key to Angiosperm Evolution?

Did Crane and Dilcher (1984) get it wrong:
Is Lesqueria elocata not an angiosperm, but an advanced Cheirolepidaceous conifer that produced carpel-like ovuliferous scales with paired stigmas?

For the Serious Researcher

The first fossil to clearly indicate that angiosperms more primitive than Cretaceous angiosperms existed hundreds of millions of years earlier in the Triassic Period.

Jurassic Freshwater Fishes

Massive Ancient Fish Kills

Nature's Pollution

An excavation and study of thousands of fossil fishes from an
Early Jurassic lake bed in southern Connecticut. See pictures
of Semionotus, Redfieldius, Ptycholepis, and Diplurus fossils.

Jurassic Pollen and Fishes

Fossil Spores, Pollen, and Fishes from Connecticut Indicate
Early Jurassic Age for Part of the Newark Group

This is the paper published in Science magazine in 1973 that radically changed the views of geologists and paleontologists regarding the presence of extensive Early Jurassic age deposits along the East Coast (and on the offshore Continental Shelf) of North America, deposits that had been erroneously dated as Late Triassic for more than a Century.

Early Jurassic Flora

PALYNOLOGICAL CONTRIBUTIONS TO THE
CHRONOLOGY AND STRATIGRAPHY OF THE
HARTFORD BASIN IN
CONNECTICUT AND MASSACHUSETTS

A 1975 study of the first Jurassic flora to be discovered on the East Coast of North America, revolutionizing our understanding of the breakup of Pangea.

"Electro-release condensation" is the release of an electron from the outer valance at the point of condensation and conversely "electro-nabbed evaporation" is the capture of an electron during evaporation. (linked with permission)
