In strata from the Late Paleozoic to the Mesozoic
to the Cenozoic, the oil shale grade increases and, hence, oil yield increases, but the size of deposits decreases.

magmatism and the Dongfeng gold metallization
Dinosaur coprolites are very large and are found only in rock that formed during the Mesozoic
groups like Enantiornithes, which had teeth and clawed wings, are not thought to have left any living descendents.
The new specimen may contain the oldest fossil embryos of Mesozoic

For almost 30 years this Symposium has documented the advances made by the scientific community in a number of lines of research that aim to give us a fuller understanding of the non-marine Mesozoic
brachiopods of Mexico- A review and some comments on their paleobiogeographic affinities and paleoecology.
The species is so old it has been described as a living fossil, with its family - the Araucariaceae - having been traced to the Mesozoic
era, which started 250 million years ago.
In keeping with the Mesozoic
theme, a local band called The Dinosaurs will perform.
Both blocks contain potential for oil and gas/condensate in Paleozoic and Mesozoic
