FIGURE 1 in Terrestrial Isopods from Spanish Amber (Crustacea: Oniscidea): Insights into the Cretaceous Soil Biota

FIGURE 1. Phylogenetic hypothesis of Oniscidea based on Schmidt (2008) and Dimitriou et al. (2019) combined with a synthesis of the Oniscidea amber fossil record. Circles indicate the known fossil records; those in red are the new records from Spanish amber, while black circles are those taxa recorded previously. Abbreviations: BA, Baltic amber (Van Straelen, 1928; Spahr, 1993; Weitschat and Wichard, 2010); BI, Bitterfeld amber (Schumann and Wendt, 1989; Spahr, 1993; Dunlop, 2010); BU, Burmese amber (Broly et al., 2015, 2016); D, Dominican amber (Schmalfuss, 1980, 1984a; the family Pseudarmadillidae = Delatorreidae has also been recorded); F, French amber (Perrichot, 2004); K, Kerala (India) amber (Srivastava et al., 2006); M, Mexican amber (Broly et al., 2017, 2018); R, Rovno amber (Perkovsky et al., 2010); S, Spanish amber (Delclòs et al., 2007; this paper). Age is approximately the same for Rovno, Baltic, and Bitterfeld ambers; the same occurs for Mexican and Dominican ambers (Solórzano-Kraemer et al., 2020). *dubious assignment.
