Extinct Animals

Yes, fossilized dinosaur skin has been found. In fact it can be seen in the Museum of Science in Boston, or at least could be when I was last there about twenty years ago (I moved out of the area). My recollection of what I saw was a large ossified part, perhaps over half, of a small dinosaur about twice the size of a cow. It looked like it might have frozen, been half thawed out, with the thawed half rotting away, and then been covered and turned to stone. At any rate about half of it was sort of intact, and the fossilized skin on it could clearly be seen.

Of course, whether anything at all, but a few stray atoms, of the original skin was still there is another question. In a case like this, my expectation is that whatever covered it probably became a matrix for its form, which remained as the original organic matter decomposed completely, leaving nothing but the solid parts like bones. Then, the ossification took place, filling the void with minerals. I don't know this happened, but it would be my expectation.

Most fossils of animal parts are bones or shells. There are a few fossils of soft tissue. It is common to find fossils of clam shells, but rare to find the clams. Clearly this is because the clams decomposed and the shells did not.

But a fossil is not even necessarily the remains of an animal or plant. It can be a dinosaur footprint, the track left by a snake, or a filled in hole dug by an insect. These kinds of fossils exist for dinosaur skin also - impressions left by the skin on mud or clay that was covered and ossified, retaining the shape of the skin.

Fossils are most often mineralized, but sometimes they are not. Amber is an example of a common fossil that is not mineralized, and it often contains insects or pollen that are pretty much made up of the original organic matter. And, even when mineralized, sometimes sufficient traces of original material remain to be instructive. I have seen fossilized feathers that were completely mineralized, but retained some of the feather's original pigmentation, so it was possible to see where stripes were on the feather. I have no idea that the dinosaur skin I saw had a color anything like what the original color was. Even if pigment remained, certainly some pigment would have disappeared, leaving an impression of color that might be about as accurate as the idea of the color of a maple leaf in summer derived from fall colors.

If the ginkgo biloba tree had become extinct, the ecosystem it inhabited could have experienced significant changes. As a unique species with specific adaptations, its absence would have disrupted interactions with local flora and fauna, potentially leading to declines in species that rely on it for food or habitat. Additionally, the loss of ginkgo trees could have affected soil composition and nutrient cycling, altering the overall dynamics of the ecosystem. This could have resulted in reduced biodiversity and changes in the structure and function of the environment.

The ivory billed woodpecker. At the end of the Civil War, the great southern riverine forests of tupelo, live oak, and cypress were clear cut over much of this species range. Southern landowners, robbed of their livlihoods by the war, sold their lands to survive to greedy northern industrial firms. The bird hangs on today in very small numbers, maybe less than 50 in the entire south.

The viperfish (Chauliodus sloani) is not classified as rare, endangered, or extinct. It is considered to be relatively common in deep ocean environments, particularly in tropical and subtropical waters. However, its deep-sea habitat makes it less frequently encountered by humans, which can lead to misconceptions about its rarity. Conservation status assessments can vary, but as of now, the viperfish is not listed as threatened.

The last Allosaurus died because it was redundant. Allosaurs as a whole didn't die off completely until somewhere in the middle cretaceous period, and they did very well up until that point. Thus, a more appropriote question might be "What did Allosaurus evolve into?" Another Allosaurid that we can't exactly pinpoint is the answer to that. There is an early cretaceous true allosaurid that was living on Australia/Antarctica, but last I heard it had not been completely identified as a new species. Of course, an American theropod like Allosaurus somehow evolving into a dwarf species in Antarctica sounds a little iffy, but Allosaurus most certainly evolved into a more specialized form in the millions of years following the end of the Jurassic.

Allosaurs as a whole (and that is including the Early Cretaceous carcharodontosaurs) went extinct due to pressure from even more specialized predators like the Tyrannosaurs and Abelisaurs (Carnotaurus and the like).

There is no 'most extinct'. Once they are gone, they're gone. The most endangered great whale is the Western Pacific Gray Whale. See Related Links.

The thylacine, also known as the Tasmanian tiger, is believed to have existed for thousands of years, with its ancestors dating back around 4 million years. However, the species itself was declared extinct in the 20th century, with the last known individual dying in captivity in 1936. Therefore, if we consider its existence as a distinct species, it was alive for a significant period, but it is no longer present today.

The elephant bird, a flightless bird native to Madagascar, is believed to have become extinct around the 17th century. While the exact date is not known, it is generally estimated to have disappeared between 1600 and 1700. Factors contributing to their extinction likely included hunting by humans and habitat destruction.

No. The Thylacine, also known as the Tasmanian tiger, was never endangered, as the various conservation status levels were not in force before it became extinct. It was moved to "extinct" status as a result of being hunted as a possible threat to livestock in Tasmania following European settlement. The last known Tasmanian Tiger died in the Hobart Zoo in 1936.

Well, the extinction of the dinosaurs makes it a lot easier for people to survive.

Nature relies heavily on adaption to carry on existing. Life forms that are unable to adapt go extinct, because when the environment around them changes they cannot keep up with the change and survive.

They're important to evolutionary biologists because members of their group are thought to have given rise to the first four-legged land vertebrates.

Most dinosaurs were killed about 65 million years ago.

I think you will find more than 5. The excesses to the virtue of religion put faith in created thing which do not deserve it: superstition, divination, idolatry, vane observance, magic and sorcery, spiritualism [and older authors cite hypnotism and "magnetism" but those were not sinful] the deficiencies in the virtue [not showing sufficient reverence, etc] are: tempting God, blasphemy, simony and sacrilege.

that it is iccey

it turns out that the password for low gravity on dino run is astrosaur, spelled like that, no capitalization. this is, in my opinion, the most fun cheat for the game because it allows you to make AMAZING jumps and it feels like you are floating in the air for a couple of seconds. its just too bad that you cant add to you permanent score when this cheat is enabled. . . . .
