Data from: An assessment of ancient DNA preservation in Holocene-Pleistocene fossil bone excavated from the world heritage Naracoorte Caves, South Australia
Although there is a long history of research into the fossil deposits of the Naracoorte Caves (South Australia), ancient DNA (aDNA) has not been integrated into any palaeontological study from this World Heritage site. Here, we provide the first evidence of aDNA preservation in Holocene- and Pleistocene-aged fossil bone from a deposit inside Robertson Cave. Using a combination of metabarcoding and shotgun next-generation sequencing approaches, we demonstrate that aDNA from diverse taxa can be retrieved from bulk bone as old as 18 600 cal a BP. However, the DNA is highly degraded and contains a lower relative proportion of endogenous sequences in bone older than 8400 cal a BP. Furthermore, modelling of DNA degradation suggests that the decay rate is rapid, and predicts a very low probability of obtaining informative aDNA sequences from extinct megafaunal bones from Naracoorte (ca. 50 000 cal a BP). We also provide new information regarding the past faunal biodiversity of Robertson Cave, including families that have not been formerly described in the fossil record from here before. Collectively, these data demonstrate the potential for future aDNA studies to be conducted on material from Naracoorte, which will aid in the understanding of faunal turnover in southern Australia.

Supplementary data for Yeoman's et al. in review "Waterfowl eggshell refines palaeoenvironmental reconstruction and multi-species niche construction at the Pleistocene-Holocene transition in the Levant"
<p>This upload contains MALDI-TOF mass spectra, averaged from replicates or as single-best spectrum, as .txt files. Data derive from archaeological eggshells samples for the paper "Waterfowl eggshell refines palaeoenvironmental reconstruction and multi-species niche construction at the Pleistocene-Holocene transition in the Levant". </p> <p>Sample preparation:</p> <p>Eggshell was recovered from multiple contexts at Shubayqa 1 and Shubayqa 6 from flotation samples [screened with 1mm mesh]. A sample of 34 eggshell fragments were selected for preliminary analysis across seven excavation contexts. Samples were processed according to Demarchi et al., (2022). Briefly, 10-30 mg of sample were ground to a powder and treated with bleach (NaOCl 12-15% w/v) for 72 hours. Samples were washed thoroughly and demineralised in 0.6M hydrochloridric acid (HCl) prior to filtration with 3000 Da Nanosep micro-ultrafiltration cells. Sulfide bonds were reduced and alkylated using dithiothreitol (1M, aqueous solution) and iodoacetamide (0.5 M, aqueous solution) and the samples were digested in trypsin overnight at 37 °C. Following digestion, peptide digests were purified using C18 Zip-tips according to the manufacturer’s directions, prior to spotting. Samples were analysed in triplicate or duplicate by MALDI-MS (Bruker Microflex MALDI-TOF mass spectrometer).</p>
