The Strangest Cambrian Creatures Ever Discovered

moncler sale It wasn’t that animals didn’t exist before this time, as they did, that made this period special. In factthe oldest worm known has been dated to be a billion years old which vastly outdates the Cambrian period, but this is a time when life was suddenly seen moncler jackets kids in great abundance and the immense variety that moncler jackets outlet online starts to approach the current population of earth. This was a time of cheap moncler strange creatures when mother nature was just starting out. If you know nothing of Cambrian life forms you might think some of them are someone’s depiction of what aliens on another planet must look like. They range from familiar to utterly bizarre. So I’m inviting my readers to come with me on a written safari to gawk and awe at some of these odd little critters.

moncler mens jackets Trilobites Trilobites are probably one of the best known Cambrian creatures. They came in hundreds, if not thousands of cheap moncler jackets outlet species, and most had an uncanny resemblance to moncler outlet online store pill bugs or certain types of cockroaches. Most of them looked rather benign and didn’t grow very big but several of these little critters evolved some very strange attributes. Today I’ll run through moncler outlet kids three of these species.Ceratarges: Ceratarges are a rare and fantastic find. They are generally unearthed near Morocco and can sell for a few hundred to a few thousand dollars. Unfortunately there’s scant little information besides their marketability out there. Still one must speculate what those extra spines were for. Perhaps this made them less likely to moncler coats for women eaten by the predators of the day. Were these moncler jacket online spines solid enough to withstand an attack or did they detach moncler outlet store like porcupine quills? Were they filled with venom like a scorpion? These are some moncler jackets men of the questions that many paleontologists would love the answer to, unfortunately without moncler coats for cheap the aid of a time machine we’re not likely to figure it out.Walliserops: Walliserop is another oddity we’re not too sure about. This little guy seems to moncler jackets cheap be a cross between a hissing cockroach and a table fork. What did he use his fork for? Since no animals exist that are remotely like this we are left to speculate. Perhaps he used it to search for and eat food. Perhaps it was part of a mating display. Perhaps only males had these (or only females!) cheap moncler jackets Perhaps it was some cheap moncler jackets wholesale sort of defense mechanism or perhaps he used it to burrow in the sand. One of the strangest moncler coats for men aspects of this one, besides his fork, is his species tendency to favor asymmetry. Most other trilobites are perfectly symmetrical but not little walliserops! They have been known to curve to one side or the other and their wee trident as well isn’t exactly a study in perfect symmetry.Dicranurus monstrosus: This aptly named trilobite has so many spines you almost can’t tell what’s what. Two amazing spines curl over it’s back in a fantastic antennae like way. Other spines jut out in every direction. like the other two trilobites mentioned he also lived in the area we now know as Morocco.

moncler outlet online Jelly Fish The oldest jelly fish actually predates the Cambrian explosion (with the oldest dating back to 500 million years)but they were around during the Cambrian as well. Being soft creatures without any bones or hard shells they are a hard find as far as fossils go but they are discovered every now moncler outlets uk and again. They still moncler jackets exist in our oceans today much as they did in the Cambrian oceans and still are some of the strangest creatures around. Most have heard that jellyfish don’t have a brain and have tossed this aside as urban legend but it is true, jellyfish do not have a brain, or a nervous system for that matter. This is because jellyfish aren’t actually one creature, rather they are a number of small organisms that are working together in a colony to make up what appears to be one creature. They are made up of 95% water and are anatomically strange. Their “mouth” is used to eat fish, get rid of moncler jackets canada wastes, and throw up sperm/eggs. At different points in their life they can reproduce both sexually and asexually. They’re quite a conundrum.

moncler outlet Myllokunmingia Fish moncler outlet canada AncestorVertebrates, animals with internal bones, have remained elusive in the early fossil records. For many years paleontologists thought that animals like fish didn’t show up until after this initial explosion moncler outlets usa of life but a new discovery in China is calling that all into question. The creature in question, Myllokunmingia, is 530 million years old and although it doesn’t have hard bones its head and several other features seem to have been made of cartilage. This moncler jackets toronto probably made the animal flexible and swift. It may have been the granddaddy of all sharks moncler jackets outlet and fish.

cheap moncler jackets AmmonitesAmmonites are one of the most abundant forms of life found in the Cambrian fossil record. They were early mollusks that evolved from animals with straight long shells. They predated the mollusks of today that include squid, octopi, and the nautilus which is their closest living relative (but probably not a direct descendant.) The various species of ammonites evolved and went extinct so fast that paleontologists often use them to date other fossils found with them. Eventually they Discount Moncler Coats would grow to enormous size, the largest specimens reaching Official Moncler Outlet ten meters in length, or moncler chicago three meters in moncler outlet usa shell diameter, but in the beginning they weren’t of any substantial size. These creatures survived several mass extinctions before most went the way the dinosaurs at the same time. Today nautiluses and other mollusks are our only living reminder they existed but that’s not to say they didn’t have fantastically long run in our planet’s evolutionary history!

cheap moncler outlet HallucigeniaAs you can tell from the name Hallucigenia is a strange “dream like” creature. It doesn’t seem to have terribly much anatomy that we can point to and be familiar with. In fact the soft blob like “head” might not actually be its head. It has both stifftentacles with pincer tips and jointed spines. If notit sired no known living day descendants so we might be pondering this one for awhile.

buy moncler jackets Horseshoe CrabHorseshoe crabs are fascinating little creatures. I know, you probably only know them as odd living room ornamentation but really there’s more to them then that! Did you know for instance that horseshoe crabs have anti freeze colored blue blood? Its copper based and used in the medical profession to test the purity of pharmaceuticals. For all you horseshoe crab lovers out there, don’t fear, though a third of their blood is harvested for this use when they crawl ashore they are returned alive and are capable of replacing their lost blood (which is usually more than a human can loose and live from!) Horseshoe crabs are anatomically a bit strange as moncler coats well. They eat worms and other small things in the sand and use their spine like tail to change direction and guide them, not to stab anything. They have 300 flat gills and some of the oldest compound eyes on record. It takes up to twelve years for them to grow to full size and usually live around twenty years although some forty year old captives have been recorded. They’re also related to spiders, oddly enough.

moncler outlet sale OpabiniaOpabinia is a fun one. Eyes actually first appeared in the Cambrian period, and they were all compound eyes (like you’d see on a fly.) Opabinia however has the current world record for the most eyes normally seen on one animal. They had five each. Why five? We have no idea. This asymmetrical number is a bit odd! It wasn’t moncler jacket outlet a big creature, only three inches in length, but it was an interesting creature. It may have used it’s trunk and pinchers to catch even smaller critters for dinner. Or perhaps it dug dinner up with it’s strange appendage. It was first discovered in the 1970s and to date only about twenty specimens have been found. It’s been an interesting animal to speculate moncler jackets on sale upon.

AnomalocarisThe Anomalocaris is the rock moncler outlet location star of the Cambrian fossil record. It was earth’s first “super predator” growing up to six feet long, an astonishing size considering most of the other living animals around were maybe the size of cockroaches.

monlcer down jackets HurdiaHurdia was moncler coats outlet another enigma to science. Like its relative the anomalocaris it was thought to be a bunch of different animals when it was found in parts. Only when a full Moncler Factory Outlet specimen was found did the big picture come to light. Even so it remains a mystery. It grew a foot and a half long and had a weird completely hollow head shield. We have no idea what this was used for. Some speculate it may have been used to help the animal go up and down in the water like a little submarine but this is just a guess. We don’t even know for certain if this animal was a predator, which is likely considering its size, or a herbivore.

moncler sale outlet BanffiaBanffia look like weird bloated tadpoles and are so strange they are currently not known to have any living relatives. They appeared in the moncler jackets mens fossil moncler outlet mall shale of Scotland in 1911 and have been baffling paleontologist ever since. moncler jackets for women It is guessed that these animals Moncler Outlet probably lived on the sea bottom and sifted food out of the sand it had swallowed, much like a sea cucumber today, but we can’t even be certain of that much. They were small animals growing only to about four inches long and may have congregated in large numbers.

cheap moncler Sea Urchins (?)I am not totally sure sea urchins are from the Cambrian period, so if you know they are not please tell me! [Someone was kind enough to comment and tell me that Sea Urchins are actually somewhat younger, having evolved 450 million years ago in the late Ordovician period. Thank you Jon!]

cheap moncler coats Well, despite the confusion I did discount moncler outlet still write about sea urchins so I think I’ll leave this bit in for now even though they’re not technically Cambrian.

moncler outlet store Sea Urchins are almost their own class, but not quite. They come in all sorts of colors (black, green, red, and purple among them) and biologists think they may be able to live for more than two hundred years. In fact even geriatric sea urchins seem to be able to spawn more sea moncler outlet urchins. They don’t have too many predators but are enjoyed by sea otters moncler outlet online and some types of eels. They themselves tend to feast on algae. They are currently being used to study moncler outlet woodbury the evolution of the immune system.

cheap moncler sale The Cambrian fossils are immensely interesting for their odd forms, but moncler coats for kids also immensely frsutrating as it is so difficult to know exactly what they looked like, how they behaved or what they were related to. All one can do is speculate but that in itself is a fun thing to do :) .
