“…Specimens of C. submagna were recovered from two localities in Podolia, Ukraine: Kasperovcy village, left border of the river Seret (type locality), and from the right escarpment of the River Dniester near the village Ivanye Zlote (Olempska et al, 2012). The type locality, part of the Chortkov/Chortkiv Horizon, underlies the second locality, which is part of the Ivanye Horizon (Filipiak et al, 2012;Olempska et al, 2012). Thus we must use the Chortkiv age as a minimum constraint on the age of C. submagna, to provide the narrowest interval of clade divergence.…”

“…Thus we must use the Chortkiv age as a minimum constraint on the age of C. submagna, to provide the narrowest interval of clade divergence. The Chortkiv Horizon comfortably lies within the middle Lochkovian stage of the Lower Devonian (Filipiak et al, 2012;Małkowski et al, 2009;Plotnick, 1999). Conodont biostratigraphy places the upper boundary of the Chortkiv Horizon at the end of the Caudicriodus postwoschmidti Biozone, the oldest conodont Biozone within the Devonian (Drygant and Szaniawski, 2012).…”

Fossil age data and molecular sequences are increasingly combined to establish a timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically disparate animal phylum, have received substantial attention, particularly with regard to questions such as the timing of habitat shifts (e.g., terrestrialisation), genome evolution (e.g., gene family duplication and functional evolution), origins of novel characters and behaviours (e.g., wings and flight, venom, silk), biogeography, rate of diversification (e.g., Cambrian explosion, insect coevolution with angiosperms, evolution of crab body plans), and the evolution of arthropod microbiomes. We present herein a series of rigorously vetted calibration fossils for arthropod evolutionary history, taking into account recently published guidelines for best practice in fossil calibration. These are restricted to Palaeozoic and Mesozoic fossils, no deeper than ordinal taxonomic level, nonetheless resulting in 79 fossil calibrations for 101 clades. This work is especially timely owing to the rapid growth of molecular sequence data and the fact that many included fossils have been described within the last five years. This contribution provides a resource for systematists and other biologists interested in deep-time questions in arthropod evolution.
