Poseidon2910 - Birds, Synapsids and Mammals

Image
 Here are the birds, Synapsids and mammals of this odd, seeded world. This is the final entry in this series, I am proud of these concepts, despite the failure of the overall project. - A beaver-like descendant of Kayentatherium, that clambers amongst kelp forests, feeding on the ever-present kelp. A giant, manatee-like descendant of Kayentatherium, which propels itself underwater with a laterally undulating tail. A seal-like descendant of Castorocauda. A sea-lion-like descendant of Castorocauda. A large platypus, that probes the sea-bed in search of worms and other small invertebrates. A streamlined, dugong-like descendant of Thalassocnus, which feeds on sea-grass in temperate waters. A giant, long-necked descendant of Thalassocnus, which swims using its broad flipper-like limbs. A pony-sized carnivorous Whippomorph, which scavenges and forages along coastlines, as well as in shallow near shore waters. A seal-shaped, limb-propelled Archaeocete swimmer. A giant, walrus-like descend...

Poseidon2910 - "Amphibians and Reptiles"

Image
 Here are the Amphibians and Reptiles, to use antiquated words, of this seeded planet. - A fair-sized, dolphin-like Trematosaur. A Trematosaur that uses its mechanoreceptor-lined snout to forage for prey on the sea-bed. A child-sized saltwater frog that lacks lungs and lives entirely on the seabed in shallow water, a lethargic ambush-predator. A large, streamlined leatherback-turtle, that can swim very fast by turtle standards. An eel-shaped, large descendant of Lialis lizards, which feeds mainly on eels and other elongated fish, in coral reefs. A giant, short-bodied Madstoiid snake that drifts passively in the open ocean, casting a shadow to attract fish and other prey. A mid-sized mosasaur that feeds by dredging the sea-bed, like a gray whale. A large open-water Thalattosaur, with a swordfish-like nose. An enormous, filter-feeding Hupehsuchian that takes the niche of baleen whales. A small Proterochampsian, that lives in coastal waters, swimming with its frog-like hindfeet. ...

Poseidon2910 - "Fish"

Image
 In this next part, I will show you the fishes, for want of a better term, of this seeded ill-concieved world. - A small lamprey, that chews with its mouth-disc and tongue, to burrow into the hide of large marine vertebrates, in order to feed. It eventually forms and lives inside a gall-like growth that develops on and under the skin. A giant, streamlined pelagic lamprey, whose mouth is adapted to prey upon small fish and squid. A 3-inch-long pelagic Conodont, that shoals in large swarms, filtering plankton as food with its array of spiny teeth. A large, short-bodied horn-shark, with large cranial horns made of dentine. A large, deep-sea shark that looks vaguely like a plesiosaur, due to its extended gill region. A 10-meter-long deep sea shark, related to dogfish, that feeds entirely on marine invertebrates. A small wobbegong that mimics a frond of kelp in order to ambush prey. A fair-sized, pelagic requiem shark that has a boomerang-shaped head, converging on hammerheads and Diplo...
