Jurassic reptiles were forced to adapt to sea level rise

Jurassic reptiles were forced to adapt to sea level rise

Science
Sept. 4 (UPI) -- New analysis of fossil teeth have offered scientists new insights into the impacts of sea level rise on Jurassic food chains. Sea levels rose considerably over the course of the Jurassic period, the 56 million years between the Triassic and Cretaceous periods. As revealed by the fossil record, some species thrived, while others were pushed to the margins. To better understand the dynamics of this upheaval, scientists studied the shapes and sizes of teeth found among Jurassic strata along the coasts of England. All of the teeth were sourced from marine sediments representing an 18-million-year period when sea levels fluctuated dramatically. The owners of the ancient teeth belonged to a diverse food chain called the Jurassic Sub-Boreal Seaway. The analysis suggests the Jur...
Earth's earliest animals were strange frond-like sea creatures from the Ediacaran period

Earth's earliest animals were strange frond-like sea creatures from the Ediacaran period

Science
Aug. 20 (UPI) -- New fossil analysis suggests the planet's earliest known animals emerged at least 571 million years ago. The new study -- published this month in the journal Paleontology -- proves members of the Ediacaran biota are indeed animals and were diversifying for several million years before the acceleration of speciation known as the Cambrian explosion. Scientists recovered the first Stromatoveris psygmoglena fossil in the mid-20th century. The frond-like sea creature baffled paleontologists for decades. Stromatoveris psygmoglena hails from the Cambrian period, but dozens of similar blob-like fossil imprints have been found among older strata -- rocks from the Ediacaran period, which lasted from 635 to 542 million years ago. Until now, scientists have struggled to understand t...

How hats were placed atop the Easter Island statues

Media playback is unsupported on your device The famous statues of Rapa Nui, or Easter Island, are best known for their deep-set eyes and long ears.They also sport impressive multi-tonne hats made from a different rock type.Quite how these pukao, as they are known, were transported and placed atop the statues has long been a puzzle.But now American archaeologists believe they have a clearer understanding. The giant hats were moved with minimal effort and resources using a ramp and rope technique, they say. "The fact that they successfully assembled these monuments is a clear signal of the engineering prowess of the prehistoric Rapanui people," said Sean Hixon, lead author and graduate student in anthropology, at Penn State. ...

1982 World Cup All-Star Team: Who were the players voted best in Spain?

Sports
The 2018 World Cup is just around the corner, so talkSPORT.com are trawling through the archives to relive past tournaments.Today we are taking a look at the 1982 edition; held in Spain and won by Italy, it is widely regarded as one of the last truly great tournaments. You had a brilliant Brazil team headlined by Zico, Socrates and Falcao, and you had the eventual champions dumping them out the finals against all the odds. Hungary equalled the largest ever margin of victory in a World Cup match when they beat El Salvador 10-1, and France and West Germany played out a semi-final regarded by Michel Platini as the ‘most beautiful game’ he ever played in. Platini was one of the stars of the tournament, but who else caught the eye in Spain? The World Cup All-Star Team is named to re...

Why you should double check your bigger paycheckWhen the new federal income tax cuts went into effect at the beginning of the year, the White House said 90% of workers should see more in their take-home pay. But a majority of CNNMoney readers said they aren't really feeling the difference in their paychecks. Of the 550 readers who responded to a questionnaire, nearly 60% said they either aren't seeing any extra take-home pay, or if they are, it's too small to improve their financial well-being. Another 11% said their take-home pay went up by between $ 100 and $ 199 per paycheck or per month, while another 9% reported getting between $ 200 and $ 1,000 extra. Those who reported getting extra money most commonly said they were using it for everything from buying gas and food to saving to p...
