Redescription Of Dolphin Skull Sheds Light On Their Origins And Evolution
2014-05-08 03:04:46

[ Watch the Video: CT Image Of The Skull Of Oldest Known Dolphin ] Society of Vertebrate Paleontology Dolphins are the most diverse family of living marine mammals and include species such as the bottlenose dolphin and the killer whale. However, their early evolution and fossil record has been steeped in mystery due to lack of good specimens. A new paper published in latest issue of the Journal of Vertebrate Paleontology re-describes the oldest species of dolphin with a new name:...

Unique Dinosaur Roamed The Desert Of Supercontinent Pangea
2013-06-25 09:03:28

April Flowers for redOrbit.com - Your Universe Online Pangaea, a single supercontinent existing from 300-200 million years ago, dominated the Earth during the Permian era with animal and plant life dispersed broadly across the land. This disbursement is documented by identical fossil species found on multiple modern continents. A new study, from the Society of Vertebrate Paleontology, supports the idea that Pangaea had an isolated desert at the center of the supercontinent with unique...

Paleontology And Development Genetics Help Piece Together Evolutionary History
2012-11-08 06:30:08

April Flowers for redOrbit.com - Your Universe Online Developmental genetics and paleontology seem worlds away from each other and the gulf between fossils and petri dishes seems insurmountable. Even the essential questions of the two disciplines are miles apart. Paleontology strives to determine "What happened in evolution?", while developmental genetics uses gene control in embryos to try to answer "How did it happen?" Scientists have been combining the two, however, with some remarkable...

Mystery Of The Flatfish Head Solved
2012-06-25 16:50:25

Those delicious flatfishes, like halibut and sole, are also evolutionary puzzles. Their profoundly asymmetrical heads have one of the most unusual body plans among all backboned animals (vertebrates) but the evolution of their bizarre anatomy has long been a mystery. How did flatfishes, with both of their eyes on one side of their head, evolve? So puzzling was the anatomy of flounders and their kin that they were used in early arguments against Darwin and his theory of natural selection....

An analysis of skeletal remains has provided new evidence that humans made it to the Western Hemisphere during the last ice age, where they lived alongside giant, now-extinct mammals, claims a new study published online Thursday in the Journal of Vertebrate Paleontology. University of Florida researchers used rare earth element analysis in order to measure the concentration of naturally occurring metals absorbed during fossilization in human and mammal remains discovered in south Florida...

Image 1 - Researchers Find New Species Of Ancient Predatory Fish
2011-09-12 11:14:53

  The Academy of Natural Sciences today announced the discovery of a new species of large predatory fish that prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land. Drs. Edward "Ted" Daeschler and Jason Downs of the Academy and colleagues from the University of Chicago and Harvard University describe the new denizen of the Devonian they named Laccognathus embryi in the current issue of the Journal of Vertebrate Paleontology....

Scientists have discovered a cave housing 15-million-year-old fossils of prehistoric marsupials in the Outback. The researchers unearthed 26 skulls from an extinct, wombat-like marsupial called Nimbadon lavarackorum, which is an odd sheep sized creature with giant claws.  The findings were reported this week in the Journal of Vertebrate Paleontology. "It's extraordinarily exciting for us," said University of New South Wales paleontologist Mike Archer, co-author of the article. "It's...

Evidence that the first widespread occurrence of terrestrial vertebrates 300 million years ago was in response to a brief episode of a globally warmer, drier climate A team of researchers from Carnegie Museum of Natural History has described a new genus and species of carnivorous amphibian from western Pennsylvania. The fossil skull, found in 2004 near Pittsburgh International Airport, was recovered from rocks deposited approximately 300 million years ago during the Late Pennsylvanian Period....

Skull fragments of prehistoric koalas from the Riversleigh rainforests of millions of year ago suggest they shared the modern koala's "lazy" lifestyle and ability to produce loud "bellowing" calls to attract mates and provide warnings about predators. However, the new findings published as the featured cover article in the current issue of The Journal of Vertebrate Paleontology suggest that the two species of koalas from the Miocene (24 to five million years ago) did not share the uniquely...

Scientists say a peculiar, bony armored amphibian prowled warm lakes 210 million years ago, catching fish and other tasty snacks with one of the most unusual bites in the history of life on Earth. Gerrothorax pulcherrimus lived alongside some of the early dinosaurs and opened its mouth not by dropping its lower jaw, as other vertebrate animals do, instead, it lifted back the top of its head in a way that looked a lot like lifting the lid of a toilet seat. Harvard University's Farish Jenkins,...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Megalonyx, meaning “Great claw,” is an extinct genus of giant ground sloths in the family Megalonychidae. The genus was endemic to North America from the Hemphillian stage of the Late Miocene to the Rancholabrean stage of the Pleistocene epoch (10.3 million to 11,000 years ago). The species, M. leptostomus, was named in 1893. It lived from Florida to Texas, north to Kansas and Nebraska, and west to New Mexico, Nevada, Oregon, and Washington. Fossils have been discovered in numerous...
