The final period of this series is the Triassic. It lasted for around 50,000,000 years from the end of the Permian to the beginning of the Jurassic period (~200mya). Earth spent a majority of the Triassic recovering from the Permian extinction. By about the middle part of the Triassic the supercontinent Pangaea began to break apart with Laurasia in the north and Gondwana in the south. Therapsids and archosaurs were the most dominant terrestrial vertebrates. During the Triassic a subgroup of Therapsids went on to become the first, true mammals. While a subgroup of archosaurs became the first flying vertebrates; the pterosaurs, and another evolved into the first dinosaurs.
The primitive dinosaurs were small and uncommon although they were destined for greatness. The Triassic dinosaurs were already outclassing the older reptiles with their new adaptations such as agility and intelligence... Soon, the Triassic will end with another mass extinction. This mass extinction will clear away many of the older species which allowed the dinosaurs to seize their global dominance when the Jurassic period rolled around. For the next 150,000,000+ years dinosaurs will dominate every single continent, live in nearly all habitats, and explode into countless different shapes and sizes. They will become Life's Greatest Success Story...
It is the last period of the Paleozoic Era and it lasted for over 45,000,000 years from the end of the Carboniferous (~300mya) to the beginning of the Triassic (~252mya).
Amniotes continued to diverse throughout the Permian and branched off into the first mammalian ancestors, turtles, lepidosaurs, and archosaurs. At this time, the planet only consisted of two main continents; Pangaea and Siberia, while many ecosystems were deserts within the vast continental interior. The early Permian saw terrestrial pelycosaurs (such as the famous sail-backs like Dimetrodon and Edaphosaurus), diadectes, and amphibians. The middle Permian witnessed the rise of primitive therapsids and more advanced therapsids in the later parts of this period. At the very end of the Permian the first archosaurs appeared and one day, in future times, will split into the crurotarsans and the dinosaurs. It is also worth mentioning that cynodonts came to be during these times and they will advance into the future as well, becoming the origins of true mammals. Terrestrial invertebrates also played a significant role in the Permian. For example, primitive relatives of cockroaches made up for roughly ninety percent of all insects in the early Permian. In the skies the main aerial predators were the ancient forms of dragonflies, but the days of their kind being giant, hawk-sized predators such as the Meganeura was all but over... At least the good news was the fact we saw the beginning of both true bugs and beetles in this time.
Unfortunately, the Permian will not end nicely... At the end of it the Earth will go through the largest mass extinction ever! Over 90% of all marine life and 70% of terrestrial life will be obliterated... All types of plants and animals were hit hard and even some of our long time favorites such as the trilobites were unable to make it out alive... However, the good news is that one day, when the planet recovers, life will continue on like it always does...
Yo guys I'm making a new account on here because the username on this account that I made when I was 12 is cringey as shit. I have another account on here that I made a couple months ago because I hated my username that I never really got around to using so I'll either go to that one or make an entirely new one. So yeah don't be scared, I won't be leaving Neo for a very long time so I'll still be able to make ya'll cringe ;)
I've already pretty much got rid of everything on here so if you're a mod feel free to delete this account!
Lasting for roughly 60,000,000 years the Carboniferous will be the next period on our long list. Carboniferous actually means "coal-bearing" in Latin and is named after the underground coal deposits that were left by the once common rainforests of this time. The land itself continued to change during this time and the continents finally joined together to create the super-continent; Pangaea.
The atmosphere during the Carboniferous has been known to contain large amounts of oxygen, 35% (an all time high) compared to today's 21%. This meant good news for the terrestrial invertebrates as this allowed them to grow to great sizes such as the dragonfly-like insect Meganeura that reached hawk sizes and the ~3 meter long millipede, Arthropluera. However, by about the middle Carboniferous the Earth experienced an extinction event: Extreme glaciation occurred which in turn dropped sea levels. The first half of this period saw a hot and humid climate while the second half felt a cooler and more arid climate. These changes started the Carboniferous Rainforest Collapse (CRC) and the vast rainforests and swampy regions mostly disappeared. Not only that, but also the amphibians, the most prominent terrestrial vertebrates at the time, didn't fair too well with this change and they were strictly limited. But with the appearance of amniotes and the first reptiles, life was able to prevail. The hard shells of amniote eggs allowed them to be safely laid on dry land and the scales of reptiles prevented their bodies from losing moisture in the new, arid conditions. Reptiles turned out to be quite successful and even branched off into a handful of different types before the close of the Carboniferous.
Lastly, in the oceans, creatures such as the trilobites became less and less common while the sharks experienced evolutionary radiation since their previous competitors, the placoderms, disappeared at the end of the Devonian.
Don't worry, this is WAY less grim than you think it is. I'm really just thinking of cutting the name "C Falcon" and making it something else.
For a little back story, C Falcon725 was my name here when I first joined the site. Since then, the 725 is gone and I just was "C Falcon." Why was I C Falcon725? It had to do with me liking Captain Falcon in Super Smash Bros. Now that I can't stand that game, I have just kind of been like "Well, Captain Falcon is a cool guy." He is, but it seems kind of silly to keep it now that I have only played F-Zero GX and despise Smash Bros.
So, I'm thinking about changing the old name. I only kept it until now because old friends wouldn't have known me by anything else. Since most have proven to be gone for good or the ones that I DID reconnect with, I ended up adding them on Steam or something, I think I should let go of my old Neoseeker past and start new with a better name.
I have thought of this for a little. Maybe not as long as others, but here's a few names I might pick.
Cap Falcon Cap'n (if the ' is allowed) CapN (if it isn't) Classic Crook Santa Claus
That's the short list. I'm tagging a few people for their idea. I dub thee Official Name Council 2017.
If you hate them all, tell me. I can just not change my name in the end.
The Devonian Period started at the close of the Silurian (~419mya) and ends at the beginning of the Carboniferous (~360mya). During this time the supercontinent of Gondwana was located in the Southern Hemisphere while the continent of Siberia was to the North with the formation of the small Euramerica in between. The two continents of Gondwana and Euramerica were already predestined to collide together in the near future...and they'll one day form another super-continent; Pangaea.
In aquatic environments the fish continued to greatly diverse, giving the Devonian Period a nickname of the "Age of Fish". During this period we see the introduction of ray-finned and lobe-finned bony fish. Also in the Devonian; placoderms were able to dominate almost all marine environments. Creatures such as the trilobites and giant coral reefs were still quite common and even more new faces emerged such as the ammonites.
Meanwhile, on land, the free-sporing vascular plants spread throughout the lands, creating vast forests across the continents. By the middle of the Devonian several groups of plants grew leaves and developed true roots. Lastly, the earliest seed-bearing plants made their distribution at the end of the Devonian.
Terrestrial arthropods secured a strong foundation in their ecosystems.
But perhaps the biggest milestone of the Devonian was when the ancestors to all tetrapods (four-limbed vertebrates) adjusted their strong pectoral and pelvis fins to form legs -- these were the amphibians. Amphibians have soft skin that must be kept damp, this prohibited them from venturing too far from the water otherwise their skin would dry out. Nonetheless, this was still a big step for life on land.
The Silurian Period lasted for ±25 million years from the end of the Ordovician Period (~444mya) to the beginning of the Devonian Period (~419mya).
As evolution progressed the very first jaws appeared among bony fish. This feature will be a great evolutionary success and will continue to evolve for hundred of millions of years into the future. Meanwhile, on land, life continued to advance little by little... Terrestrial arthropods such as Pneumodesmus were first found in the Silurian rocks. The first vascular plants also evolved in the second portion of the Silurian, plants such as the small Cooksonia (as seen in the image above). Aside from these, terrestrial life will not significantly conquer the land until the Devonian Period...
The Ordovician will be the next period we cover. It spans from the end of the Cambrian (~485mya) to the beginning of the Silurian (~444mya) and just like its predecessor the Cambrian, the Ordovician will also be jam packed with new life... The marine environments consisted of various algae, graptolites, trilobites, brachiopods, cephalopods, some corals, crinoids, gastropods, primitive fish, and conodonts. The Ordovician truly marked the beginning of true vertebrates as well as fish, these fish were known as ostracoderms. Ostracoderms were jawless, armored fish with bony shields on their heads, small plate-like scales on their tails, and slit-like mouths. An example of this would be Astrapis. The Ordovician also started the colonization of the land. Fossils of some early, terrestrial arthropods are known in addition to microfossils of the cells, cuticles, and spores of early land plants -- although these were restricted to the shorelines...
However, the planet itself also had it's fair share of action... Europe, South America, Africa, Antarctica, and Australia formed the supercontinent Gondwana and was slowly moving towards the South Pole during the Ordovician Period. Meanwhile, North America was mostly submerged in the ocean and was stuck straddling the equator. As the Ordovician started coming to a close severe glaciation occurred in Africa, resulting in global sea levels to drop. This glaciation played a role in the disturbance of ecosystems worldwide and another mass extinction.
Woke up, had my daily lunch date with J. Daniels a little earlier than usual today.
Had to continue what seemed like a perpetual inebriation if I was going to make it until it was time for my 4 hours of sleep. Things were starting to get better, but I guess that was too unusual for me to let it continue. I felt like a stranger in my own body. Like if I was missing the inside joke that was my own existence.
Oh squiggly line in my eye fluid. I see you lurking there on the periphery of my vision. But when I try to look at you, you scurry away. Are you shy, squiggly line? Why only when I ignore you, do you return to the center of my eye? Oh, squiggly line, it’s alright, you are forgiven.
