The Evolution Of Jaws Based On A 325M-Year-Old Shark-Like Fossil
2014-04-17 07:20:53

April Flowers for redOrbit.com - Your Universe Online Despite having retained their basic "sharkiness" for millions of years, modern sharks have less to tell us about the early evolution of jawed vertebrates—including humans—than was previously thought. A new study led by the American Museum of Natural History, based on the skull of a newly discovered 325-million-year-old shark-like species, reveals that modern sharks are quite evolutionarily advanced when compared to early...

Vertebrate Study Reveals The Evolution Of The Face
2014-02-13 09:19:21

[ Watch the Video: Animation Sequence of Romundina Fish Fossil ] Brett Smith for redOrbit.com - Your Universe Online Faces allow us to recognize each other almost instantaneously – so much so that they are the primary feature on our driver’s licenses and other identification cards. A study published on Wednesday in the journal Nature has revealed new details on the evolution of the jaw – a major defining structure in the evolution of the face. In the study, a team of...

Fish Relatives Surprise Scientists
2013-07-18 04:53:01

Susan Bowen for redOrbit.com - Your Universe Online Scientists have used genetic data to create a comprehensive evolutionary family tree, or phylogeny, for "spiny-rayed fish," a category that encompasses about a third of all living vertebrate species. They were quite surprised to find out just who was related to whom in the fish world. The researchers, who published their findings in the Proceedings of the National Academy of Sciences looked at 10 genes in more than 500 fish species...

Mystery Of The 25-Foot Ancient Spiral-Toothed Shark Solved?
2013-02-27 11:12:41

Brett Smith for redOrbit.com - Your Universe Online Imagine a 25-foot-long shark, but instead of having a typical set of jaws, it packs a chainsaw-like ℠tongue´ full of razor-sharp teeth ready to slash through prey with ease. While it sounds like something straight out of a Killer B Movie, it is anything but. A group of American researchers has described just such a creature that lived about 270 million years ago based on the animal´s fossilized spiral set of teeth....

Researchers Find Origins Of Teeth Much Older Than Previously Believed
2012-10-18 12:57:12

Michael Harper for redOrbit.com — Your Universe Online It´s likely the question “how long have humans had teeth?” has never entered into many normal and sober minds. Scientists and, more specifically, odontologists, are a different breed, however, and have wondered about the origins of teeth for many years. Now, thanks to a particle accelerator and a very, very dead fish, scientists have concluded that teeth may be much older than they had previously assumed....

New Zealand Reptile Chews Food Unlike Any Other On The Planet
2012-05-30 08:56:23

[ Watch the Video ] Scientists studying one of New Zealand´s most iconic reptiles have found that it chews its food in a way unlike any other animal on the planet, challenging the popular perception that complex chewing ability is linked to high metabolism. The tuatara, a beak-headed lizard-like reptile that is the sole living member of a family of reptiles that was widespread during the age of the dinosaurs, is able to slice through its food like a “steak knife” would....

Skull Of Jurassic Sea Creature Shows That Even Dinosaurs Had Arthritis
2012-05-16 10:28:45

Arthritis, an often debilitating joint disorder that affects millions and millions of people around the world, may have also caused pain and discomfort for dinosaurs and other ancient reptiles more than 150 million years ago, according to new research from the University of Bristol. Researchers, led by Bristol´s Dr. Judyth Sassoon, were fascinated to find a degenerative condition similar to arthritis in the jaw of a female pliosaur -- an ancient sea creature that lived during the Late...

'Head-first' Diversity Drove Vertebrate Evolution
2011-12-21 09:32:25

New study of fish fossil records near extinction events contradicts previous models The history of evolution is periodically marked by explosions in biodiversity, as groups of species try out a wide range of shapes and sizes. With a new analysis of two such adaptive radiations in the fossil record, researchers have discovered that these diversifications proceeded head-first. By analyzing the physical features of fossil fish that diversified around the time of two separate extinction...

Orthodontic Problems Linked To Food Gathering
2011-11-24 05:41:05

A new study has found that many of the orthodontic problems faced by people in industrialized nations are due to their soft modern diet. The research from the University of Kent tested the theory that the transition from a hunter-gatherer to an agricultural subsistence strategy has had a knock-on effect on the growth and development of the human skull and lower jaw. The team compared the shape of the skull and lower jaw of 11 globally distributed populations against models of genetic,...

Scientists have identified a critical step in the evolution of filter-feeding whales' enormous mouths. These whales, otherwise known as baleen whales or mysticetes, have feeding adaptations that are unique among mammals, in that they can filter small marine creatures from huge volumes of water.  The whales accomplish this by using their "loose" lower jaw joints, which enable them to produce a vast filter-feeding gape. A new study of this ancient jawbone has overturned a long-held belief...

Angler, Lophius piscatorius
2012-04-02 16:12:16

The Angler, (Lophius piscatorius), also known as the Fishing-frog, Frog-fish, or Sea-devil, is a species of monkfish in the family Lophiidae. It is found in coastal waters of the northeast Atlantic, from the Barents Sea to the Strait of Gibraltar, the Mediterranean and the Black Sea. This species comprises a significant commercial fishery in parts of its range. The Angler has a very large, broad head that is flat and depressed. The rest of the body appears to be a mere appendage. The wide...
