Crocodiles Abounded Five Million Years Ago
2013-05-22 09:36:49

April Flowers for redOrbit.com - Your Universe Online The largest number of crocodile species is currently found in northern South America and Southeast Asia, and as many as six species of alligator and four true crocodiles exist. However, no more than two or three ever live alongside one another at any one time. Approximately nine to five million years ago, however, it was a different story. A total of 14 crocodile species existed, with at least seven of these occupying the same area...

Crocodiles’ Sensitive Faces Help Understand Ancestors

Watch the video "Measuring a Crocodile's Smile" redOrbit Staff & Wire Reports - Your Universe Online The ultra-sensitive nerves in the faces of crocodilians could help biologists understand how both modern and ancient animals interact with their environment, according to a new study in this month´s edition of The Anatomical Record. These nerves are so sensitive that they can detect changes in a pond when a single droplet of water hits the surface several feet away....

Alligator Relative Traveled Across Ancient Land Bridge

April Flowers for redOrbit.com - Your Universe Online The Isthmus of Panama uplifted 2.6 million years ago to form a land bridge connecting North and South America. This bridge has long been thought to be the crucial step in the interchange of animals between the Americas. Armadillos and giant sloths moved up into North America and ancient relatives of modern horses, rabbits, foxes, pigs, cats, dogs and elephants moved down into South America. A new study from the University of Florida...

The Black Caiman is currently attempting a comeback from 90% extinction caused by hunting and habitat loss, but is threatened by another crocodilian. An article in the March 2013 issue of the journal Herpetologica examines the dietary relationship between these two crocodilians. Lawrence, KS (PRWEB) February 12, 2013 Herpetologica — As the Black Caiman, a relative of the alligator, attempts a comeback from near extinction, its biggest threat is not humans or predators, but another...

Crocodiles And Alligators Are Actually Sensitive Creatures
2012-11-08 14:12:17

Brett Smith for redOrbit.com - Your Universe Online Crocodiles and alligators are well-known for being cold-blooded and having thick skin, but new research from a pair of Vanderbilt University scientists has shown that the ancient reptiles can be quite sensitive. More specifically, the scientists demonstrated that these reptilian predators have small pigmented domes that dot their skin-- conveying a sense of touch is even more responsive than that of humans, according to the pair´s...

[ Watch the Video ] "If it can't bite you, it's not interesting,” jokes David Ray an evolutionary biologist at Mississippi State University (MSU). Ray and his team of researchers study alligators, crocodiles, flies, bats and other animals. Ray stated of the risky work, "Oh, it's great. I mean, there's just a thrill.” The team, comprised of researchers from many different universities, is undergoing studies on genome mapping of alligators and crocodiles, funded by the...

Crocodiles can kill with the strongest bite force measured for any living animal, according to a report published Mar. 14 in the open access journal PLoS ONE. The authors of the study, led by Gregory M. Erickson of Florida State University, measured the bite forces, as well as tooth pressures, for mature adults from all 23 living crocodilian species, including crocodiles, alligators, caimans, and gharials. The strongest biter was a saltwater crocodile at 3,700 pounds. It also generated...

New Prehistoric Crocodile Species Discovered

[ Watch the Video ] Researchers have discovered a new species of a 95 million year old prehistoric crocodile. The "Shieldcroc" was part of the Mesozoic Era, which some scientists are starting to call the "Age of the Crocs," University of Missouri researcher Casey Holliday said. "Aegisuchus witmeri or 'Shieldcroc' is the earliest ancestor of our modern crocodiles to be found in Africa," Holliday, co-researcher and assistant professor of anatomy in the MU School of Medicine, said in a...

The Nile crocodile is a species that was identified by ancient Egyptians. Genetic analysis done by a group of geneticists using samples taken from species throughout the animal's range and including DNA from mummified crocodile remains indicates that more than one species is known by this name. "This paper provides a remarkable surprise: the Nile crocodile is not a single species, as previously thought, but instead demonstrates two species - living side-by side - constitute what has been...

Rare find alters origins and distribution of Terminonaris; first home was Texas and North America "” not Europe By Margaret Allen, SMU Making its first appearance in Texas, a prehistoric crocodile thought to have originated in Europe now appears to have been a native of the Lone Star State. The switch in origins for the genus known as Terminonaris is based on the identification of a well-preserved, narrow fossil snout that was discovered along the shoreline of a lake near Dallas. The...

The Gharial, Gavialis gangeticus, is one of two surviving members of the family Gavialidae. The Gharial (also known as gavial) is found in small numbers in India and other small populations in the Kaladan and Ayeyarwady River basins in Myanmar. Most gharials are adapted to calmer areas in deep fast moving rivers. They rarely leave the water and do so only to bask in the sun or nest on sandbanks near the river. The gharial is the second-longest of all living crocodilians. A large male can...

The Spectacled Caiman, Caiman crocodilus, is a crocodilian reptile found in much of Central and South America. It lives in a range of lowland wetland and river habitat and can tolerate salt water as well as fresh. Due to this adaptable behavior, it is the most common species of caiman. Males of this species are between 6 and 8.2 feet long, while females are smaller, usually around 4 and a half feet long. The species' common name comes from the bony ridge between the eyes, which give the...

The False Gharial or Malayan Gharial, Tomistoma schlegelii, is a fresh-water reptile, resembling a crocodile. This animal is native to six river systems in Sumatra and Malaysia. It is also found in Borneo, Java, Vietnam, Thailand and possibly Sulawesi. In Thailand, the Gharial has not been seen since 1970. There have also been fossils found in Southern China that indicate it once survived there as well. The female Gharial usually matures at 17-118 inches in length . The False Gharial,...
