I seek to change this up a bit for the remake. So, what's all here?
Sea VII: The Silurian
Southeast Asia, 420 MA ago (Generic Silurian locale)
Hazards: Eurypterids, Brontoscorpio, MegamastaxAh, yes, good ol' Silurian. That time in Earth's history when vertebrates started taking bites out of stuff and giant arthropods roamed the waters. Plants had just started to take to the land, and the world's attempt at recovering from getting Love Sign ~ [Master Spark]-ed to the face by a black hole 24 MA earlier has produced some real monsters.
- Lungmenshanaspis yunnanensis, one of those very trippy-looking fish called the galeaspidans. I'm sincerely sorry for not featuring more of them in the Silurian segment of Re:WWM, but I'm making up for this here. This species has three long spikes on its head. Both of the galeaspidans are shown as benthic filter-feeders.
- Eugaleaspis liuhuashanensis, another galeaspidan, but a more tame-looking one. Of course, it still has a weird boomerang-shaped cephalic shield. Just... go home, evolution. You're drunk.
- Cyathaspsis banksii, a cyathaspid fish common to the area, returning from Re:WWM. Like the galeaspids, this is mostly just a redshirt for the local predators. Unlike them, however, it's much less of a bottom-feeder. Nigel uses a dead Cyathaspis scrounged up from the beach as bait to attract some of the local sea life.
- Megamastax amblyodus, an early jawed fish. Megamastax is a major predator of the local sea life. They can be a bit nippy, so Nigel and the crew brought shark suits.
- Brontoscorpio anglicus, a gigantic scorpion. Brontoscorpio is shown as the snake to Megamastax's mongoose. The two quite often prey upon each other.
- Rhinocarcinosoma dosonensis, a rather unremarkable eurypterid, next to the giant Pterygotus, anyway. Rhinocarcinosoma is shown as a benthic predator, and mostly is here for ambience. A large Rhinocarcinosoma is used as bait for larger animals here, like Pterygotus.
- Pterygotus anglicus, a massive eurypterid common to (somewhere other than) the area. Pterygotus is as long as an adult human, and is the apex predator around here.
- Mongoceras sp., an orthocone common to the area. Mongoceras is mostly shown as a filter feeder, and for ambience.
- Entelognathus primordialis, another primitive jawed fish. Entelognathus is an early form of those strange fish of the Devonian we know as "placoderms". It looks a fair bit tamer than those wild-looking ones from later on.
Sea VI: The Permian
Brazil, 270 MA ago (Pedra do Fogo Formation, Mangrullo Formation)
Hazards: Eugeneodonts, PrionosuchusThis place is... new. Yeah, new. I would've featured the Triassic seas of the Besano Formation, but I decided that the weird fish, mesosaurs, and giant amphibians of these sites need more love. Anyway, this strange inland sea has produced some strange and fascinating creatures for Nigel and the crew to dive with.
- Prionosuchus plummeri, a massive archegosaurid amphibian. This bus-sized amphibian plays the role of Cymbospondylus in the original series, as a large predator that appears towards the end of the segment. The Prionosuchus spooks the Helicoprion Nigel was observing take down a siphonophore and then moves on to smaller, easier prey...
- Helicoprion sp., another giant of the Permian seas. Helicoprion is about 9 metres long, and mostly feeds on soft-bodied animals like fish and the occasional siphonophore. Nigel hitches a ride on the fin of a Helicoprion, but has to get off due to it approaching a large, potentially stinging, siphonophore.
- Various background fish, including lungfish, palaeoniscids, and the utterly indescribable petalodonts, show up too. Petalodonts are mostly seen swimming around in the local coral reefs, as are lungfish and palaeoniscids, but the petalodonts get more time in the sun due to their utter wackiness.
- An unidentified, speculative, siphonophore. This is mostly here to give large prey items to the big bois of the Permian seas of Brazil, and makes sense, since siphonophores tend to not fossilize.
- Stereosternum tumidum (identified in-universe as "mesosaur"), a small, nippy parareptile common to the area. The mesosaurs are shown as an early example of tetrapods returning to the sea. Mesosaurs have been found in both South America and Africa, which were connected at this point in time (although everywhere else was also connected, because Pangaea).
- Anisopleurodontis pricei, a large eugeneodont, not as big as Helicoprion but still huge. Anisopleurodontis is shown as a major predator of the smaller animals here.
- Timonya anneae, a smaller amphibian than the giant. Timonya is shown as a lower-grade predator than Anisopleurodontis.
- Tiarajudens eccentricus, a strange non-dicynodontian anomodont from the area. Tiarajudens bears two massive tusks, which is shown here to be a sexually dimorphic trait: they're smaller in the females. Anyway, Tiarajudens is mostly seen ambling about on the beaches. The crew takes a liking to them, due to their comical appearance. They're more like their dicynodont descendants than other basal anomodonts.
Sea V: The Devonian
Ohio, 375 MA ago (Cleveland Shale)
Hazards: Sharks, DunkleosteusSome familiar faces will be here, and some new ones. In any case, the Cleveland Shale is home to a diverse assemblage of fish, including the T. rex of the Devonian. One question is on the minds of Nigel and the crew: can Dunkleosteus bite through a shark suit?
