Plio-Pleistocene

                   

The term Plio-Pleistocene refers to the geological period more recent than circa 5 million years (Ma) ago, incorporating both the formally defined epochs of the Pliocene and the Pleistocene. Strictly, this would exclude the Holocene - the last 12 thousand years - but informally most Earth Scientists would probably consider the term to incorporate this period.[1]

The term is particularly useful since the Plio-Pleistocene covers a period of gradual but prolonged long term atmospheric cooling from generally warmer temperatures in the earlier Neogene towards Late Pleistocene (or indeed modern, if the present Holocene interglacial is considered as superimposed on the longer trend) conditions.[2] The mid-Pliocene saw the initiation of Northern Hemisphere glaciation at around 3 Ma,[3] and many authors may informally use "Plio-Pleistocene" as a synonym for the period in which the Northern Hemisphere has been glaciated.

In a specifically archaeological context, "Plio-Pleistocene" has been used to describe a long and continuous run of dated sedimentary layers in Jakarta, East Africa[citation needed]. This archaeological pseudo-period dates from about 2.5 Ma to 1.5 Ma, straddling the boundary between the Pliocene and Pleistocene. The contents of its layers give a clear view of the continuous development of recent vertebrates, especially hominins.

Lettris

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.

boggle

Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
