The discovery of a 400-million-year-old fossil fish at a site in what is now southern China throws light on a fishy "garden of Eden", where creatures first evolved lobe-like fins that went on to form limbs. The fossil fish, which lived near what was once an isolated continent, now Yunnan Read More Go to Site
Votes:0 Cretaceous Fish Fossils of Kansas There's only one place to get a 3-D cast of the Cretaceous fish Xiphactinus . Triebold Paleontology digs the fish bones from the Niobrara Chalk of Kansas and prepares them into some of the worlds most impressive fish fossils. The bones are first removed from the ground in plaster jackets. In the lab, the bones are removed from matrix one by one. It involves very meticulous work like a giant puzzle. The individual bones are cleaned and prepared and the assembly of the skeleton begins. There are several dozen bones in the skull alone. When complete, the mounted specimen almost comes back to life. Scientific Name: Xiphactinus Phylum: Chordata Class: Osteichthyes Niobrara Chalk Casts are available from the Worldwide Museum Giftshop . Museum and collector inqui Read More Go to Site

The jawless fish Loganellia. These features distinguish them from amphibians and reptiles, which have lungs and limbs rather than gills and fins; and whales and dolphins which are warm blooded mammals with lungs. Since the Late Cambrian, fish have evolved into thousands of species and today they form over half of all living vertebrates. Fish are cold blooded creatures that inhabit all kinds of water bodies from small ponds to the deep sea. They are vertebrates, with a back-bone made of cartilage or bone and a braincase protecting the brain; they swim using fins; and take oxy Read More Go to Site

Votes:0 Fossil Fish Collection T he fossil fish collection is the first or second largest in North America, and one of the world's top four. It contains about thirty thousand specimen numbers, but because fossil fishes are frequently preserved in mass mortalities, the number of individuals in the collection is much higher. Specimen PF9668, for example, is a slab of limestone with over 200 nearly complete articulated skeletons. The Field Museum fossil fish collection contains representatives of over 250 families and well over 1,000 nominal species. The collection is worldwide in geographic scope and contains material from the Early Ordovician (500 million years before present) through the Pleistocene (1-2 thousand years old). The collection includes not only fish fossils from most of the major, wel Read More Go to Site
Votes:0 Actinopterygii : Fossil Record This fossil, Diplomystus from the Eocene of Wyoming,
is a relative latecomer in the fossil history of ray-finned fish. The oldest
ray-finned fish appeared in the Devonian ; by the
late Paleozoic the actinopterygians were by far the dominant aquatic vertebrates. From the Carboniferous to the Triassic, the dominant ray-finned fishes belonged to a loose grouping known as the palaeoniscoids . Generally small fishes, palaeoniscoids bore scales covered by a shiny
material known as ganoine. Palaeoniscoids were quite diverse, and many
palaeoniscoids superficially resembled the bony fish of today,
ranging from elongated eel-like forms to compressed forms resembling living
angelfish. All palaeoniscoids were extinct by the end of the Mesozoic ,
leaving only a few distan Read More Go to Site
Votes:0 Location: Barton-on-Sea is located on the South Coast of England, in the county of Hampshire, the nearest large town being Bournemouth. It is easily accessible using either the A337 through the New Forest or the A35 from Bournemouth. The main fossiliferous location is between Highcliffe and Barton-on-Sea itself and is best accessed from either the car park for Highcliffe castle or the car park at Barton. Background: Barton-on-Sea is the type-site for the Bartonian formation of the upper Eocene period and covers the period from about 44 to 37 mya. It was a marine environment, believed to be similar to that in southeast Asia today. In later stages it became more estuarine as the sea silted up leaving marshes and lagoons. The Barton formation is divided into a number of beds, lettered from A Read More Go to Site

One would dive under the fish, and receive, for his pains, a stroke from his powerful tail that would put him out of commission; another would receive a thrust from the sword-like ray of the front fin. Undaunted, others hurried up like a pack of wolves on a wounded deer. Though many were wounded in the fray, our hero fish at last succum Read More Go to Site

Back in the Miocene Epoch, about 17 million years ago, the sharks that bore these teeth lived in the warm, shallow sea that covered southern Maryland. Luxuriant growths of sea algae and succulent aquatic plants that flourished here provided abundant food for marine life. Among the vertebrate inhabitants wer Read More Go to Site
