Dinosaurs Died Agonizing Deaths

Fossilized dinosaurs often have wide-open mouths, heads thrown back and tails that curve toward the head. Paleontologists have long assumed the dinosaurs died in water and the currents drifted the bones into that position, or that rigor mortis or drying muscles, tendons and ligaments contorted the limbs.

“I’m reading this in the literature and thinking, ‘This doesn’t make any sense to me as a veterinarian,’” said Cynthia Marshall Faux, a veterinarian-turned-paleontologist at the Museum of the Rockies.

Faux and a colleague say brain damage and asphyxiation are the more likely culprits.

A classic example of the posture, which has puzzled paleontologists for ages, is the 150-million-year-old Archaeopteryx, the first-known example of a feathered dinosaur and the proposed link between dinosaurs and present-day birds.

“Virtually all articulated specimens of Archaeopteryx are in this posture, exhibiting a classic pose of head thrown back, jaws open, back and tail reflexed backward and limbs contracted,” said Kevin Padian, professor of integrative biology and curator in the Museum of Paleontology at the University of California, Berkeley. He Faux (pronounced “Fox”) published their findings this week in the journal Paleobiology.

Some animals found in this posture may have suffocated in ash during a volcanic eruption, consistent with the fact that many fossils are found in ash deposits, Faux and Padian said. But many other possibilities exist, including disease, brain trauma, severe bleeding, thiamine deficiency or poisoning.

“This puts a whole new light on the mode of death of these animals, and interpretation of the places they died in,” Padian said. “This explanation gives us clues to interpreting a great many fossil horizons we didn’t understand before and tells us something dinosaurs experienced while dying, not after dying.”

Also, because the posture has been seen only in dinosaurs, pterosaurs and mammals, which are known or suspected to have had high metabolic rates, it appears to be a good indicator that the animal was warm blooded, as other research has suggested. Animals with lower metabolic rates, such as crocodiles and lizards, use less oxygen and so might have been less traumatically affected by hypoxia during death throes, Padian said.

Padian acknowledged that many dinosaur fossils show signs that the animal died in water and the current tugged the body into an arched position, but currents cannot explain all the characteristics of an opisthotonic pose.

Ramar Sethu is a Man-Made Sea Ridge: Study

BANGALORE: A recent scientific research using archeo-astronomy tools has sought to prove that Ramar Sethu is not natural but a man-made sea ridge. It�s a testimony to the civil engineering marvel of an ancient civilisation, that stands even today as a man-made accretion over a natural formation in the sea.

DK Hari, conceptualiser of Bharath Gyan, a NGO which is in to collating specific, scientific knowledge of India has, at a presentation on �Historical Rama� here on Saturday, said the records compiled together talk about Ramar Sethu�s usage until 1480. But it went into disrepair after a debilitating cyclone in 1480, he pointed out.

Hari said Rama indeed was a historical hero and lived nearly 7200 years ago. To rescue Sita from the clutches of Ravana, Lord Rama and his team built the bridge. With the help of Nala as the architect, he designed and executed the project along with the help of �Vanara� tribe. So Rama named the bridge after Nala.

The Sethu came to be known as Adam�s bridge as Sri Lanka�s first Muslim leader, Adham, reached the island from India crossing over this bridge. The Europeans found it easy to call it Adam�s Bridge rather than Nala Setu or Ramar Sethu.

Hari said that the scientific corroborating evidences is the outcome from the analysis of astronomical skycharts using modern scientific tools, geological surveys and research, archaeological research, historical notes of travellers, published Government Gazettes and historical records of the British.

Today, there is a natural sea ridge formation over the seabed linking the land masses of India and Sri Lanka. Hari said “the sea level has risen nine feet above the bridge in the last 7000 years. The bridge is covered under the layers of hardened sands.”

About the execution of the bridge, Hari said that Nala identified a linear chain of islands and converted it with land fills and used it for building the 35-km bridge in just five days at a ratio of 100:10 with an average breadth of 3.5 km as found by NASA and also mentioned in the ancient scriptures.

The dilapidated structure still stands testimony to the engineering marvel of that period. It comprised 103 small patch reefs lying in a linear pattern with reef crest, sand and intermittent deep channels. The space left between the stones allows water to pass through it.

Thus, the knowledge of pore pressure was incorporated in the bridge, Hari said.
