T. Rex's Killer Bite Revealed
2012-02-29 11:47:25

Researchers from the University of Liverpool have revealed that the jaw muscles of Tyrannosaurus rex suggest that the dinosaur had the most powerful bite of any living or extinct animal. The measurement, based on a laser scan of the dinosaur´s skull, showed that its bite was equivalent to up to 13,000 pounds -- four times more than previously estimated. Publishing their findings in the journal Biology Letters, the team scaled up the skulls of a human, an alligator, a juvenile T....

Scientists use basic principles of underwater optics, physics to understand predator-prey interactions A new study examining the complex and dynamic interactions between white sharks and Cape fur seals in False Bay, South Africa, offers new insights on the physical conditions and biological factors underlying predator-prey interactions in the marine environment. University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science assistant professor Dr. Neil Hammerschlag, and a...

A fragment of whale rib found in a North Carolina strip mine is offering scientists a rare glimpse at the interactions between prehistoric sharks and whales some 3- to 4-million years ago during the Pliocene. Three tooth marks on the rib indicate the whale was once severely bitten by a strong-jawed animal. Judging by the 6 centimeter spacing between tooth marks, scientists believe the attacker was a mega toothed shark Carcharocles megalodon, or perhaps another species of large shark which...

Scientists off South Africa's Cape were surprised as a half-ton great white shark jumped into their research boat with them, reports The Guardian. The marine researchers were caught off-guard as the 10-foot-long shark leapt into their boat, becoming trapped on deck for over an hour. The incident took place off Seal Island, near Mossel Bay, on South Africa's Cape coast. The crew used sardines to attract the sharks, which are known for bursting through the surface as they prey on seals....

A new study co-authored by University of Florida researchers provides details on the first cookiecutter shark attack on a live human, a concern as warm summer waters attract more people to the ocean. The study currently online and appearing in the July print edition of Pacific Science warns that swimmers entering the cookiecutter's range of open ocean tropical waters may be considered prey. The sharks feed near the surface at night, meaning daytime swimmers are less likely to encounter them....

HONOLULU, Dec. 6, 2010 /PRNewswire-USNewswire/ -- Scientific recommendations for improving information on population status and fishing of sharks will be considered this week at the annual meeting of the Western and Central Pacific Fisheries Commission (WCPFC). Scientists are recommending that the WCPFC adopt a three-phase shark research plan, identify species of concern, and make reporting on shark catches mandatory. Shark catch reporting has proved a challenge for some WCPFC member...

Adolescent great white sharks may be too weak to capture and kill large marine mammals The jaws of adolescent great white sharks may be too weak to capture and kill large marine mammals, according to a new study published in the Journal of Biomechanics by an international team of scientists. The researchers also found that, unlike mammals, sharks can maintain high bite forces no matter how widely their jaws are open, thanks to a unique jaw muscle arrangement that has helped them to be among...

A fisheries group decided on Saturday that half-a-dozen species of endangered sharks hunted on the high seas to satisfy a burgeoning Asian market for sharkfin soup are now protected in the Atlantic. The International Commission for the Conservation of Atlantic Tunas (ICCAT) said that scalloped, smooth and great hammerheads, along with oceanic white tip, cannot be targeted or kept if caught accidentally. Three other types of hammerhead sharks are also included in the ban, including smalleye,...
