I was going to add the plush fossil amphibians and reptiles, but a new lot came in to those Japanese shops, including more amphibians and reptiles, but more invertebrates, so I am adding in the new invertebrates first.
Grypania spiralis - a eukaryotic alga from 2.1 billion years ago. It is by far the oldest known multicellular organism.
Eoandromeda octobrachiata - an Ediacaran organism consisting of eight radial spiral arms. It is considered to be the earliest known fossil of an adult animal.
Crumillospongia - a middle Cambrian sponge from the Burgess Shale.
Naraoia - a Cambrian blind trilobite with no lobes (unlike the rest of the trilobites).
Canadaspis - a Cambrian early ancestor of the crustacean, related to shrimps and lobsters. Canadaspis is the most common fossil in the Burgess Shale.
Habelia - a Middle Cambrian arthropod.
Haplophrentis carinatus - a small Cambrian hyolithid (hyolithids may be molluscs).
Amiskwia sagittiformis - a Middle Cambrian
worm-like invertebrate.
Nemagraptus gracilis - a middle Ordovician Graptolite. The Ordovician graptolites were very
important for mapping in the Victorian goldfields.
