Abstract
Widespread igneous rocks were emplaced in the eastern South China Bolck (SCB) from the Jurassic to the Cretaceous period. These rocks include granitoids and rhyolites, and minor mafic and rare intermediate igneous rocks, of unclear geodynamic origins. We compiled 780 published igneous rock ages to age-code a 1:500, 000 digital geological map, which was then used to analyze the spatio-temporal evolution of the associated magmatism. Regional igneous rocks can be divided into four major emplacement episodes: 190–175 Ma, 165–155 Ma, 145–125 Ma, and 105–95 Ma, with the first two episodes dominated by intrusive rocks emplaced in the Jurassic in inland South China (~550–1200 km away from the trench), and the latter two episodes mostly eruptive rocks emplaced in the Cretaceous along coastal areas (~400–800 km away from the trench). To investigate the association of these events with the history of subduction, we calculated the slab flux along eastern China using two pub

A DINOSAUR footprint discovered on the Yorkshire coast has been described as a real Jurassic giant.
Scientists say the discovery, the largest ever in the northern county, could have been left behind by a 30ft meat-eater, possibly a megalosaurus.

Archaeologist Marie Woods, who made the discovery, said: I had originally gone to collect shellfish for dinner, but got completely distracted by this beast!
Dinosaurs, despite living millions of years ago, have been in the news a lot recently. In January, a four-year-old girl found a prehistoric footprint in south Wales.
The world as we know it today is almost inconceivable without the rich and colourful landscapes created by plant life. Among them are flowering plants, or angiosperms, which are by far the most diverse and abundant group of plants, making up over 80% of all known species, including all our staple food crops.
But the world was not always like this. There was a time when plant life was almost exclusively green. Then, in the time of the dinosaurs, the world burst magnificently into bloom.
Flowers blessed our environment with chromatic vibrancy, but they also upturned food chains and elbowed out their nonflowering predecessors. Little is known about how ecosystems reacted to this sudden blossoming. But now, a tiny beetle, preserved in amber for 99 million years, has provided a valuable clue about how insects first began nourishing themselves on a colourful new platter of plants.
