The colonization of the oceans by calcifying pelagic algae [PDF]

open access: yesBiogeosciences, 2019
The rise of calcareous nannoplankton in Mesozoic oceans has deeply impacted ocean chemistry and contributed to shaping modern oceans. Nevertheless, the calcareous nannoplankton colonization of past marine environments remains poorly understood.

History of investigations of fossil algae in Croatia

open access: yesGeologia Croatica, 2008
Investigations of fossil algae in Croatia began in 1907 with the very first description of the Permian dasyclad Mizzia velebitana from Mt. Velebit by Austrian geologist Richard Schubert. This was followed by Julius Pia’s investigations (1920, 1925),
