The first appearances of aragonite and calcite skeletons in 18 animal clades that independently evolved mineralization during the late Ediacaran through the Ordovician (~550 to 444 million years ago) correspond to intervals when seawater chemistry favored aragonite and calcite precipitation, respectively. Skeletal mineralogies rarely changed once skeletons evolved, despite subsequent changes in seawater chemistry. Thus, the selection of carbonate skeletal minerals appears to have been dictated… Expand
Seawater Chemistry, Biomineralization and the Fossil Record of Calcareous Organisms
Oscillations in seawater chemistry have characterized at least the last 600 million years of earth history. Three phases of aragonite seas have been separated by two of calcite seas, the former dueExpand
Calcite and aragonite seas and the de novo acquisition of carbonate skeletons.
TLDR
The results suggest that calcite and aragonite seas do have a strong influence on carbonate skeletal mineralogy, however, this appears to be true only at the time mineralized skeletons first evolve. Expand
Eve of biomineralization: Controls on skeletal mineralogy
Carbonate mineralogies have oscillated between aragonite and calcite seas through geological time, proposed to be due mainly to secular variation in the magnesium/calcium ratio driven by changingExpand
Response of the Elemental Chemistry of Carbonate Phases to Secular Change in Ocean Chemistry.
Abstract Calcium carbonate is the dominant inorganic mineral precipitate of the global ocean and by no coincidence, it is also the most abundant mineral produced by life. Secular variation in theExpand
The role of SO4 in the switch from calcite to aragonite seas
Throughout the Phanerozoic, the primary inorganic marine calcium carbonate mineralogy oscillated between calcite and aragonite, reflecting changes in seawater chemistry. These variations in seawaterExpand
The long‐term impact of magnesium in seawater on foraminiferal mineralogy: Mechanism and consequences
Foraminifera are unicellular protists, primarily known for their calcium carbonate shells that provide an extensive fossil record. This record, ranging from Cambrian to present shows both majorExpand
Paleoecology of the earliest skeletal metazoan communities: Implications for early biomineralization
TLDR
Observations support the view that skeletonization was promoted by the rise of substrate competitors and bilaterian predators, in predominately carbonate platform and reef environments. Expand
Experimental investigation of calcium carbonate mineralogy in past and future oceans
Inorganic marine calcium carbonate formation and mineralogy varies significantly concurrent with the solution composition. During the Phanerozoic, due to oscillations in the seawater composition,Expand
Phanerozoic trends in skeletal mineralogy driven by mass extinctions
Changes in ocean chemistry that favoured the precipitation of aragonite or calcite are thought to have influenced the skeletal mineralogy of marine calcifyers. An investigation of the originalExpand
Demise of Ediacaran dolomitic seas marks widespread biomineralization on the Siberian Platform
The trigger for biomineralization of metazoans in the terminal Ediacaran, ca. 550 Ma, has been suggested to be the rise of oxygenation or an increase in seawater Ca concentration, but geochemical andExpand
