570 vanished lives

304Precambrian

Millimetre-wide ribbons form centimetre-scale coils in Proterozoic rocks.

305Precambrian

Cell division and branching resemble living red algae and may record early sexual reproduction.

307Precambrian

Branching spherical microfossils may push the fungal record toward one billion years.

409Precambrian

Repeatedly branching cell filaments push green-plant history toward one billion years.

410Precambrian

Cell partitions and internal platelets were interpreted as very ancient red-algal evidence.

411Precambrian

A lobed multicellular thallus was proposed as an early red-algal body.

412Precambrian

Long carbonaceous ribbons resemble soft algae but lack diagnostic organs.

418Precambrian

Branching cellular filaments show complex photosynthetic life before abundant animals.

473Precambrian

Complex branching and septa make it a candidate early eukaryote or fungus.

474Precambrian

Cup-like bodies linked by filaments have been read as fungi or a microbial colony.

477Precambrian

Circular carbon films may represent a giant single-celled eukaryote traditionally called an alga.

478Precambrian

Sausage-shaped carbon films may be macroalgae or another early eukaryote.
