The most famous fossil specimen of Xiphactinus contains the almost-intact remains of an obscure, 10-foot-long Cretaceous fish. Essentially, Myllokunmingia resembled a bulkier, less streamlined Haikouichthys; it had a single fin running along its back, and there's some fossil evidence of fishlike, V-shaped muscles and pouched gills (whereas the gills of Haikouichthys seem to have been completely unadorned). The importance of Pholidophorus is that it was one of the first "teleosts," an important class of ray-finned fishes that evolved during the early Mesozoic Era. A frustrated son tries to determine the fact from fiction in his dying father's life. Cheirolepis (Greek for "hand fin"); pronounced CARE-oh-LEP-iss. If you think your fish may be constipated, try changing to a different food-- maybe one with a higher vegetable content. It's one of the ironies of paleontology that short-lived, bizarre-looking creatures get all the press, while boring genera that persist for tens of millions of years are often overlooked. Bigfish Gear is a fishing apparel and graphic design company based in Darwin, Northern Territory, Australia. Have more questions? Middle Jurassic (180-160 million years ago), Large eyes; whip-like tail; protruding dental plates. They are perhaps the best example of how poor habitat and care shortens the lifespan of aquarium fish. Yet another of the prehistoric fish that prowled the rivers and oceans of the Devonian period, Coccosteus had a well-armored head and (even more important from a competitive standpoint) a beaked mouth that opened wider than that of other fish, allowing Coccosteus to consume a wider variety of larger prey. The Ordovician and Silurian periods, over 400 million years ago, were the heyday of the jawless fishes--small, mostly harmless bottom-feeders like Astraspis and Arandaspis. See an in-depth profile of Haikouichthys, Heliobatis (Greek for "sun ray"); pronounced HEEL-ee-oh-BAT-iss. ), The late Devonian Materpiscis is the earliest viviparous vertebrate yet identified, meaning that this prehistoric fish gave birth to live young rather than laying eggs, unlike the vast majority of viviparous (egg-laying) fish. The two most popular species of fish—bettas and goldfish—are at opposite ends of the spectrum. Fish fillet are battered and served with freshly sliced potato crisps or premium skin-on fries. Goldfish are on the other end of the lifespan spectrum. See an in-depth profile of Leedsichthys, Late Jurassic-Early Cretaceous (160-140 million years ago), About one to 6 feet long and a few to 25 pounds, Thick, diamond-shaped scales; peglike teeth. In fact, the jaws of Entelognathus may turn out to be a kind of paleontological "Rosetta Stone" that allows experts to reframe the evolution of jawed fish, the ultimate ancestors of all the world's terrestrial vertebrates. As common as Ceratodus was in prehistoric times, though, its closest living relative today is the Queensland lungfish of Australia (whose genus name, Neoceratodus, pays homage to its widespread ancestor). See an in-depth profile of Bothriolepis, Cephalaspis (Greek for "head shield"); pronounced SEFF-ah-LASS-pis. The majority of goldfish are not properly cared for and as a result, live only a few years. There's a reason the discovery of a living coelacanth in 1938 caused such a sensation--these primitive, lobe-finned fish swam the earth's seas during the early Mesozoic Era, over 200 million years ago, and the odds seemed slim that any could have survived down to the present day. Saurichthys (Greek for "lizard fish"); pronounced sore-ICK-thiss. Titanichthys (Greek for "giant fish"); pronounced TIE-tan-ICK-thiss. This prehistoric fish is well-known enough to have been featured in an episode of the BBC's Walking with Monsters, though the scenarios presented (of Cephalaspis being pursued by the giant bug Brontoscorpio and migrating upstream to spawn) seem to have been concocted out of thin air. With its forked tail and mackerel-like build, Hypsocormus was one of the speediest of all prehistoric fish, and its powerful bite would have made it unlikely to wriggle off a fishing line; considering its overall agility, it may have made its living by pursuing and disrupting schools of smaller fish. The largest specimen, which was examined in 1851, measured 12.3 m (40 ft) long and weighed 16 tonnes. The lifespans of common aquarium fish species span a broad gamut, as you can see. The Devonian Cheirolepis could also open its jaws extremely wide, allowing it to swallow fish up to two-thirds of its own size. (Oddly, the lungfish of the Devonian period weren't directly ancestral to the first tetrapods, which evolved from a related family of lobe-finned fish.). The prehistoric fish Gyrodus is best known not for its almost comically circular body--which was covered by rectangular scales and supported by an unusually fine network of small bones--but for its rounded teeth, which point to its having had a crunchy diet of small crustaceans or corals. It's unknown whether Pteraspis was a bottom-feeder like its ancestors; it may well have subsisted on plankton hovering near the water's surface. Technically, probably not: this creature likely had a primitive "notochord" rather than a true backbone, and its skull (another anatomical feature that characterizes all true vertebrates) was cartilaginous rather than solid. 11838 out of 29435 found this helpful. This can be explained by the "missing link" status of this late Carboniferous vertebrate, which possessed characteristics of both cartilaginous and bony fish.
