[item=Dickinsonia vendian]
Can we talk about this item? i think its actually terrifying. a few months ago i was reading about it and i just got stabbed by fear because what is this??? there's a possibility it may have been able to [i]move[/i] because trails have been found around their fossils.

they've been found milimeters to almost 5 feet in length. also, there's just something about this that scares me so much.

and the description is correct - its place in the animal kingdom is disputed, though it is mostly agreed to be in animalia due to its resemblance to a living polychaete family, spintheridae. it's a little hard to analyze since it only exists in the fossil record as an impression, rather than an actual preserved body

i dont know. i just dont like this and if i saw one of these irl i'd stamp on it and then skeedaddle
Culinary scholars debate whether this creature was animal or fungus. If you ask the tundra dragons it's definitely a fungus, while the mirrors unanimously agree animal.

I love them :) Looking at some of those early lifeforms is like looking at aliens, it's great imo. Though there are plenty of animals around today that are equally weird and alien, like seasponges and siphonophores and such. I just love the fact that we share a planet with creatures so different to us ^^

imagine just this 5-foot long shag rug aggressively wibbling at you at like 10 mph

Were you expecting a modicum of rust?

Comment of the day right here.
Hopefully it isn't too late for me to add to the discussion here... Recently, paleontologists checked for cholesterol molecules in Dickinsonia and found more more cholesterol molecules in the fossils than the rock above and bellow the fossils. Cholesterol is only really found in animals, so... Seems like the Mirrors were right after all! I wonder if the FR team will update the description?
"The researchers found that greater than 97% of the sterols in the Dickinsonia sample were cholesteroids—27-carbon compounds that are present in almost all animals in the form of cholesterol, a key component of animal cell membranes. The cholesteroid found in the fossils was cholestane, which the scientists call the molecular fossil of cholesterol because it is the molecule to which cholesterol degenerates over hundreds of thousands of years.
Meanwhile, the sandstone above and below the Dickinsonia tissue contained predominantly 29-carbon molecules called stigmasteroids, indicative of the green algae film surrounding the fossil. Trace amounts of ergosteroids, 28-carbon molecules, were also present both in and around the fossil in small amounts."

So either it ate algae, or it had an (endo)symbiotic relationship with algae? Neat. It's like a little ocean roomba. :D
