## Fossil occurrences of scleractinian (stony) corals from the Paleobiology Database

### Description

Example dataset to illustrate the package's basic functionalities.

### Usage

    corals

### 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.
