Raising the Standard in Fossil Calibration

The Fossil Calibration Database is a curated collection of well-justified calibrations, including many published in the journal Palaeontologia Electronica. We also promote best practices for justifying fossil calibrations and citing calibrations properly.

    [CalibrationID] => 244
    [NodeName] => Testudines
    [HigherTaxon] => Reptilia
    [MinAge] => 155.6
    [MinAgeExplanation] => The holotype of <i>Caribemys oxfordiensis</i> de la Fuente and Iturralde-Vinent, 2001 (MNHNCu P-3209) from the Oxfordian Jugua Formation of Cuba is a total group pleurodire
and thus placed inside crown Testudines has been universally
accepted (e.g., de la Fuente and Iturralde-Vinent, 2001; Gaffney et al., 2006; Joyce, 2007; Sterli and de la Fuente, 2011; Anquetin, 2012). Thus the minimum constraint on the age of crown Testudines is placed at the top of the Oxfordian (155.7 ± 4.0 Ma; Gradstein et al., 2004; Ogg et al., 2008) at 155.6 Ma.
    [MaxAge] => 251.4
    [MaxAgeExplanation] => A constraint for the oldest possible age of the turtle crown must encompass <i>Proterochersis robusta</i>, even though its status as a crown turtle is highly questionable. The Lower to Middle Triassic has produced just one total group testudine, <i>Odontochelys semitestacea</i> Li et al., 2008, and we see no reason to doubt its placement as the oldest unambiguous stem-turtle (Anquetin, 2012). Rich Permian fossil sites worldwide have failed to yield anything that resembles a crown turtle, beyond the enigmatic <i>Eunotosaurus africanus</i> Seeley, 1892, which generally appears to serve the role of an early stem turtle well (Lyson et al., 2010). We therefore place our hard maximum at the base of the Triassic (251.0 ± 0.4 Ma; Gradstein et al., 2004; Ogg et al., 2008) at 251.4 Ma.
