Format

A data.frame with 29775 observations and 38 variables:

genus

Genus names of the occurrences. Cross referenced with a compiled table, the simplified version of this can be found in the supplementary material of Kiessling and Kocsis (2015).

collection_no

The number of the collection of the occurrence in the PaleoDB.

family

Family name of the occurrence.

abund_value

Abundance value.

abund_unit

Unit of abundance values.

reference_no

The reference number of the occurrence in the PaleoDB.

life_habit

The lifestyle of the occurring taxon.

diet

The diet of the occurring taxon.

country

Country of occurrence.

geoplate

Plate id of the occurrence.

lat

Present day latitude of the occurrence.

lng

Present day longitude of the occurrence.

paleolat

Reconstructed paleolatitude of the occurrence.

paleolng

Reconstructed paleolongitude of the occurrence.

period

Period of origin.

epoch

Epoch of origin.

subepoch

Subepoch of origin.

stage

Geologic stage of the embedding rocks.

early_interval

Early interval name registered in the PaleoDB dynamic time scale.

late_interval

Late interval name registered in the PaleoDB dynamic time scale.

max_ma

Maximum estimated age based on the PaleoDB dynamic time scale.

min_ma

Minimum estimated age based on the PaleoDB dynamic time scale.

stg

Bin number in the stage-level timescale stages.

ten

Bin number in the PaleoDB 10 million year resolution timescale tens.

env

Environment of the occurrence: reefal (r), non-reefal (nr) or unknown (uk), based on keys.

lith

Substrate of the occurrence: carbonate (c), siliciclastic (s) or unknown (uk), based on keys.

latgroup

Latitude of the occurrence: tropical (t) or non-tropical (nt).

bath

Inferred depth of the occurrence: deep (deep), shallow (shal) or unknown (uk), based on keys.

gensp

The binomen of the occurrence.

ecology

Symbiotic status of the occurring coral: zooxanthellate (z) or azooxanthellate (az, including apozooxanthellates).

ecologyMostZ

Symbiotic status of the occurring coral, incorporating the uncertainty of inferred symbiotic status. This variable includes assignment with the maximum likely number of zooxanthellate genera.

ecologyMostAZ

Symbiotic status of the occurring coral, incorporating the uncertainty of inferred symbiotic status. This variable includes assignment with the maximum likely number of azooxanthellate genera.

growth

Growth type of the coral: colonial or solitary.

integration

Integration of corallites from the scale of 0 to 4. solitary corals are marked with 0s.

Details

This particular dataset was used in a study by Kiessling and Kocsis (2015). All occurrences of Scleractinia were downloaded from the Paleobiology Database (PaleoDB, http://www.paleobiodb.org/) on 23 September 2014, originally comprising 32420 occurrences. They were than cross-checked with data from Corallosphere (http://corallosphere.org). See the article text for details.
