In contrast, non-extrusive salt has remained below producing horizons, but has had an effect on structure and sedimentation in most of the Mesozoic
Scientists report a new fossil specimen that belongs to Chaohusaurus (Reptilia, Ichthyopterygia), the oldest of Mesozoic
marine reptiles that lived approximately 248 million years ago.
Dinosaurs dominated over mammals in terrestrial ecosystems throughout the Mesozoic
Science & Technology Published: Updated: May 7, 2012 20:11 May 7, 2012 20:25 WASHINGTON: In a major new climate finding, researchers have calculated that dinosaur flatulence could have put enough methane into the atmosphere to warm the planet during the hot, wet Mesozoic
During the Mesozoic
Era, or Age of Dinosaurs, Australia was home to a wide range of dinosaur species.
Massive outpourings of lava, particularly those in the deep ocean, spurred bursts of evolution early in the Paleozoic era, about 550 million years ago, and in the middle of the Mesozoic
era, around 200 million years ago, claims biologist Geerat J.
Relatives of the chambered nautilus, ammonites filled the seas during the Mesozoic
era, the age of the dinosaurs.
BNM considers the Greater Akkulka area has significant exploration potential, with extensions of both the shallow gas exploration targets and the deeper Mesozoic
To probe the origination question, Jablonski turned to a vast data set, compiled by himself and a colleague, concerning the 42 marine invertebrate orders known to have appeared in the fossil record sometime in the Mesozoic
, the most recent 250 million years of Earth's history.
This terrane is intruded by a number of Mesozoic
intrusions and related copper-gold-molybdenum deposits such as Kemess, Copper Mountain, Mount Polley, Lorraine, Mt.
The presence of Mesozoic
and Permo-Triassic formations discovered in 1992 in South Pars, together with a pre-Permian possibility, aroused the interest of foreign firms.
If, as the shocked quartz suggests, the Chicxulub feature formed during a bolide crash, it will rank as one of the largest impact craters known on Earth -- a fitting honor for the agent that apparently closed the curtain on the Mesozoic
era, known as the Age of the Reptiles, and cleared the stage for the rise of the order Mammalia.
Birdsongs of the Mesozoic
, one of Boston's most prolific and original bands, headlined the festival that drew hundreds of spectators.
Indeed, paleontologists use the Permo-Triassic event as a dividing line to separate the Paleozoic ("old life") era from the Mesozoic
("middle life") era.
