retiolitinae: Cladogram and Range Data for the Retiolitinae

Description

The majority rule consensus cladogram for 22 genera from the Retiolitinae, a clade of Silurian retiolitids, along with discrete time interval data taken from the same publication (Bates et al., 2005). Additional character state data are included for three major, binary-state morphological traits.

Source for morphological character data: Collected for Bapst and Mitchell, in prep.

Details

Interval dates were taken from Sadler et al. (2009). These zones were not a 1-1 match to those in Bates et al., so it took some merging and splitting by the package author, so buyer beware. Character data are from an in prep manuscript containing character data for certain major morphological innovations of graptoloids, coded for a large number of genera based on an extensive survey of the published descriptions. The character data presented here is a small subset of the full dataset.
