Next to temporal fenestra, there are loads of other skeletal features that ally a fossil with Amniotes or more accurately with either Synapsids or Sauropsids. I don't know each and every one of these features, but I know that many of these are scientifically agreed upon, since there is a whole clade of Parareptilia, animals which have no temporal fenestrae, yet, are Amniotes, and even more accurately are allied more closely to Sauropsids than to Synapsids, for example the mysterious aquatic Mesosaurus, which appears to be the most basal Sauropsid, yet, has a skull configuration more similar to that of Synapsids. It would be funny if we discovered a third lineage of amniotes that is neither synapsid nor sauropsid.

Projects Punga: A terraformed world with no vertebrates Last one crawling: The last arthropod
ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)
Potential ideas- Swamp world: A world covered in lakes, with the largest being caspian sized.

Quotes "Arthropod respiratory systems aren't really "inefficient", they're just better suited to their body size. It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif

since there is a whole clade of Parareptilia Since when was Parareptilia an actual clade? Aren't parareptiles just a wastebasket taxon used for dumping all the reptiles that don't fit into any of the known reptile groups?

Me  Forum user Uncanny Gemstar drew what is supposed to be a me. Thanks! Spoiler: click to toggle As they walk in, they're greeted by a small, poorly kept pathway leading to a poorly constructed Japanese-style gate. Behind this, a small field made up of corn, rice, wheat, potatoes, among other plants is contrasted by large piles of books, as well as a few rather out of place looking laptops. Off in the corner, a small woman, with long, striped, and strikingly colorful socks, no shoes, unremarkable denim shorts, a large, fancy black coat, arm warmers, glasses, a tuque, and somewhat unkempt, mid-length blue-and-pink-streaked red hair, is rummaging through a trash bin, located behind a sign saying "employees only". She continues this for a while (walking behind a wall to change her outfit now and then), until one of her visitors coughs. Startled, she looks up, apologizes, and grabs a handful of textbooks and novels before daintily running off to join them. What, you want me to tell you what these mean?

Even though he is our creator, that does not afford him the right to take our lives on a whim. But that is the thinking of a homs. He is a god. Such morals cannot apply to gods.

But Souls are delicious. They're like bacon - they taste good on anything. But if you eat them, you completely remove them from existence! They can't move on or... or be reincarnated! Huh. I never really gave it much thought. Besides, what do you mean by reincarnation anyway? You know, being reborn as someone or something else. Which means different body, different memories, different experiences, yes? So isn't being reborn as "something else" the same as being "removed from existence"? I... I... eating souls isn't right! That depends on your definition of "right". All living things survive by eating other living things. So what? You're a god. You should be above all that! Gods are above living things, which doesn't necessarily mean we care about them.

Would eliminating both "Tetrapodomorpha" and "Tetrapoda" and introducing "Amphibia" for anything more closely related to Homo Sapiens than to Lungfish work?
I mean, it seems contradictory at first because Amniotes don't have "two kinds of life" which is the definition of the word "Amphibia", but if we look at it from an evolutionary standpoint we are peramorphic amphibians with extra embryonic membranes, for whom the pedomorphic tadpole stage degraded to a point that it doesn't show up as a fully functional lifeform during embryonic development.

I don't that's a good idea. "Everything closer to homo sapiens than lungfish" would include kenichthys, eusthenepteron, rhizodonts, and a bunch of other regular fish. I still think a node based tetrapoda is the best way to go. Here the best way to do it Tetrapodamorpha (every thing closer to tetrapods than lungfish -Tetrapoda (stuff with four, recognizable feet) --Eutetrapoda (crown tetrapods)
To give an existing analogy
Avemetatsaralia (everything closer to birds than crocodiles) --Avialae (birdy things) ---Aves (crown birds)

except that's the point - either we include various lobe-fins, or we exclude critters with legs and toes. (not sure what you mean by "regular"...you kept saying there's no such thing) By "regular fish" I meant "typical looking fishy fish". Say it either has to be crown bases or total crown plus stem based is flawed logic. On one hand, it would include kenichthys which we can all agree sure as hell aint a tetrapod. On the other hand, it would exclude pederpes which definitely is a tetrapoda. Going by this logic, dinosauria should include all of avemetatsaralia.
I still stand by my conclusion that a node based tetrapoda is the best way to go. It's no different the the node based dinosauria, and I don't see anyone contesting that definition.

Eutetrapoda could be the crown group

What do you think about this hypothetical phylogenetic tree?
Rhipidistia -Dipnoi (Lungfish) -Tetrapodomorpha --Basal tetrapodomorpha ('Walking Fish' with no extant descendants) --Tetrapoda (Temnospondyli+Lepospondyli+Amniota) ---Temnospondyli ---Eutetrapoda (crown group Frogs+Princes) ----Lepospondyli -----Lissamphibia ----Reptiliomorpha -----Amniota ------Synapsida ------Sauropsida
An alternative I've been theorizing:
Tetrapoda (Temnospondyli+Lepospondyli+Amniota) -Temnospondyli (traditional strict divide between tadpole and adult form, likely no Allantois, completely fish-like eggs) -Reptiliomorpha (beginnings of the amniotic membranes, starting with the Allantois) --Lissamphibia (some tendency towards pedo- or peramorphy e.g. pedomorphic Axolotl, peramorphic forest frogs) --Pedoperamorphia (elimination of either the tadpole or the adult stage) ---Pedomorphia (Lepospondyli, adult form eliminated) ---Peramorphia (tadpole form eliminated) ----Amniotiformes (e.g. Diadectomorpha) ----Amniotes

Here's my idea.
Rhipidistia -Dipnoi -Tetrapodomorpha --Various "fishes" (rhizodonts ect) --Tetrapoda (feet with toes) ----Basal Tetrapoda (Ichthyostega, Tulerpeton, Pederpes, ect) ----Eutetrapoda (crown tetrapods) -----Temnospondyli ------Lissamphibia (I heard a temnospondyl affinity is starting to take over) -----Lepospondyli -----Reptiliamorpha(Everything closer to ammniotes) ------Various reptiliamorphs ------Amniota -------Synapsida -------Sauropsida

I thought not. It’s not a story the newbies would tell you. It’s a forum legend. Lyvatan was an admin of the forum, so powerful and so wise he could use science to influence the human imagination to create life… He had such a knowledge of the forum that he could even keep the ones he cared about from leaving.Speculative Evolution is a pathway to many abilities some consider to be unnatural. He became so powerful… the only thing he was afraid of was losing his admin power, which eventually, of course, he did. Unfortunately, he taught his apprentice everything he knew, then his apprentice banned him while he was offline. Ironic. He could save others from leaving the community, but not himself.

Me  Forum user Uncanny Gemstar drew what is supposed to be a me. Thanks! Spoiler: click to toggle As they walk in, they're greeted by a small, poorly kept pathway leading to a poorly constructed Japanese-style gate. Behind this, a small field made up of corn, rice, wheat, potatoes, among other plants is contrasted by large piles of books, as well as a few rather out of place looking laptops. Off in the corner, a small woman, with long, striped, and strikingly colorful socks, no shoes, unremarkable denim shorts, a large, fancy black coat, arm warmers, glasses, a tuque, and somewhat unkempt, mid-length blue-and-pink-streaked red hair, is rummaging through a trash bin, located behind a sign saying "employees only". She continues this for a while (walking behind a wall to change her outfit now and then), until one of her visitors coughs. Startled, she looks up, apologizes, and grabs a handful of textbooks and novels before daintily running off to join them. What, you want me to tell you what these mean?

Even though he is our creator, that does not afford him the right to take our lives on a whim. But that is the thinking of a homs. He is a god. Such morals cannot apply to gods. So you think we should just shut up and die?! If that is the fate decided by a god. You are mistaken if you think we will simply accept such a fate and wait to die. We'll never stop fighting. Not till the end. To Zanza, the outcome is the same. Thus your logic is flawed.

But Souls are delicious. They're like bacon - they taste good on anything. But if you eat them, you completely remove them from existence! They can't move on or... or be reincarnated! Huh. I never really gave it much thought. Besides, what do you mean by reincarnation anyway? You know, being reborn as someone or something else. Which means different body, different memories, different experiences, yes? So isn't being reborn as "something else" the same as being "removed from existence"? I... I... eating souls isn't right! That depends on your definition of "right". All living things survive by eating other living things. So what? You're a god. You should be above all that! Gods are above living things, which doesn't necessarily mean we care about them.
