Fossil occurrences of scleractinian (stony) corals from the Paleobiology Database
Description
Example dataset to illustrate the package's basic functionalities.
Usage
data(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: - colonialor- solitary.
- integration
- Integration of corallites from the scale of 0 to 4. - solitarycorals 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, https://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.
