When did Cyanobacteria Begin to Fix Nitrogen?

  For much of the earth history, cyanobacteria were the only source of biogenic oxygen and a major source of fixed carbon and nitrogen. However, it is still not clear when cyanobacteria began to fix nitrogen. The finding of new filamentous cyanobacterial fossil from ca. 1000–720 million-year-...

Heterogenous oceanic redox conditions through the Ediacaran-Cambrian boundary limited the metazoan colonization

  Paleoenvironments (glaciation, atmospheric and oceanic oxygenation) associated with the biodiversification
  The Cambrian explosion of diverse bilaterian clades is considered to have proceeded in three phases preserved in the fossil record: (1) the appearance of basal metazoan phyla in Lat...
 
Sclerite-covered taxa and early trochozoan evolution

  Reconstruction of Orthrozanclus elongata n. sp. in life
  Orthrozanclus is a shell-bearing, sclerite covered Cambrian organism of uncertain taxonomic affinity, seemingly representing an intermediate between its fellow problematica Wiwaxia and Halkieria. Attempts to group these slug-like ta...
