Evolution Timeline

LIST OF GROUPS EVOLVED IN THE NEOEDIACARAN (0my - 50my) (in chronological order based on first appearance of group):


○ 0-10myh

• Micro tube sponges - Sponges with more branching structures, converged with sps coral growth formation.
• Upside down golden jellyfish - Golden jellyfish that live upside down in estuaries, morphologically very similar to their ancestors and to the real upside down jellyfish.
• Slingshot worms - nematodes that use their pharanx to filter feed ○ 10-20myh
• Wind dispersal mangroves - Mangrove trees with flowers adapted for wind dispersal instead of pollination and lesser developed seeds adapted more to survive in terrestrial habitats.
• Stabworms - Very diverse macroscopic Enoplan nemerteans
• Velcrocyte nemerteans - nemerteans with specialized cells
• Terror Anemone - Attracts prey with chemicals and ambushes it
• Joker zoanthid - A very fast growing zoa
• Walking Gorgonians - Gorgonians that have polyps on the ventral side of the colony and favor longer growth instead of branching growth. They walk on the sea floor with tentacles very slowly.
• Choanoflaggellate colonies - Large benthic and planktonic colonies of choanoflaggellates, later evolve to incorporate bad tastes and poisons to deter predators.
• Tabulate corraline algae - Calcified algae that grows in table coral-like structures, only living tissue on top side.
• Sponge-Eating Tardigrades - Parasites that specialize to eat individual cells of sponges, especially young colonies.
• Rugose zoanthids - Photosynthetic and non photosynthetic zoanthids with calcified skeletons on their undersides for protection.

○ 20-30myh

• Spongeroot - Intertidal kelp with primitive vascular system.
• Veinvermi - Slingshot worm descendants with calcified cuticles and a branched pharynx
• Blipworm - Pelagic stabworm descendants with two backbones (sort of).
• Gorgonophores - Pelagic descendants of Walking Gorgonians similar to siphonophores.
• Platytoda - Advanced clade of xenacoelomorphs.


○ 30-40myh

• Macrotifers - A large group of rotifers that grow through out their life and reach sizes above an inch. Descended from Bdelloid rotifers originally from river environments. Split into Motifers and Sessifers.
• Croissant Worms - Nemertean worms that develop a calcified shell.
• Golden hydra - neotenic golden jellyfish polyps.
• Calcified Gorgonians - Gorgonians with skeletons made of aragonite. Depending on species they can grow in branched patterns, flat wedged patterns, and palm leaf patterns.
• Dendrogorgonians - Typically non photosynthetic, completely soft branching corals with fewer and larger polyps.
• Ephyrozoans - Neotenic golden hydra ephyra that have become benthic scavengers and predators.
• Palm Zoanthid - Long stalked solitary zoa.
• Bristle tooth jelly - Jellies with baleen arms that stick out in front of the bell.
• Flapped Jellies - Golden jellyfish descendants that live in open waters and have flat broad shaped arms for more efficient sunlight absorption.
• Microjelly - small predatory jellyfish that lives near other larger jellies and eats their parasites.
• Lighthouse jellyfish - Flapped jellies with floating bells, toxic flesh, and varied zooxenthellae populations within their tissues.

○ 40-50myh


• Terrestrial Kelp - Macroalgae which have grown to the size of trees in colder environments.
• Leechroots and other terrestrial mangroves - Diversity of plants that are derived from wind dispersal mangroves. Make up 99% of terrestrial plant diversity.
• Limpacoelomorphs - Shelled xenacoelomorphs that live in aquatic and terrestrial environments.
• Advanced Motifers - Mostly marine, dominant nekton of Alluvius. Includes Sarcoptifers and Flapifers.
• Attachiferans - Loriciferans that attach to Motifer gills.
• Advanced Sessifers - Mostly marine, sessile reef builders with colonial and solitary varieties.
• Stepgrove - Low to the ground terrestrial mangrove which forms the steppe on Alluvius.

Coral Reefs suffered the most from tectonic plate shifts and climate change

LIST OF GROUPS EVOLVED IN THE RHIZOPHOREAN (50myh - ???) (In chronological order based on first appearance of group):
