Taxonomic identification of bone fragments in resin-embedded sediment blocks through palaeoproteomics

ABSTRACT: Identifying the taxonomy of bone fragments in resin-embedded archaeological sediment blocks can provide information about our past at a microstratigraphic resolution. Here, we first explore the effects of resin impregnation on modern bones, and find minimal effects on taxonomic identifications, but an increase in oxidation-related PTMs. We thereafter apply the method on Pleistocene resin-embedded sediment blocks from the archaeological sites of Bacho Kiro, La Ferrassie, and Quinçay. For two out of three sites, the taxonomic identifications are highly successful, reflecting a faunal composition previously identified at the site. For the last site, Quinçay, we find poor protein preservation in the sediment block that was sampled and a lower success rate of taxonomic identifications. Our results show that palaeoproteomic information can be derived from sediment blocks, allowing study of the past at a much higher resolution.

Enhancing ZooMS applications with MALDI-FTICR mass spectrometry on Pleistocene material showing variable collagen preservation

Project description:Advances in high-throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have addressed the issue of intense skeletal fragmentation at Palaeolithic archaeological sites, which hinders morphological identification. However, the challenge of variable collagen preservation persists. We aim to evaluate the potential of two mass analyzers TOF vs FTICR to propose novel options to enhance the ZooMS workflow. Type 1 collagen (COL1) was extracted from 89 archaeological bones from the site of Le Piage (France, 37-34 ka cal BP). Three distinct ZooMS protocols were used: an acid-free method (AmBic) and two demineralizations (HCl and TFA), combined with MALDI-TOF and MALDI-FTICR instruments. The first offers rapid and cheap analysis, while the second provides higher resolution. Taxonomic identifications were made by peptide mass fingerprinting (PMF). Finally, LC-MS/MS was applied to verify 26 low-collagen samples identifications.

Taxonomic identification and sex determination of Bos and Bison teeth using low-invasive high-resolution mass spectrometry

Project description:Differentiating between the genus Bos and Bison from fossil bones and teeth can be difficult and even impossible due to taphonomic deterioration, which can also muddle the identification of the sex of the animal. Both are key issues for palaeobiological and palaeoecological studies, as the two species are generally considered having quite similar spatial distributions but distinct ecological preferences, and likely similar social behaviours with males separated from female groups during most of the year. However, identifications are usually limited to “Bos/Bison” and “Sex indeterminate”, which severely limits interpretations. Here, we propose a low-invasive mass spectrometry method for simultaneous taxonomic and sex determination of Bos and Bison teeth, with successful application on a Middle Pleistocene large bovid teeth from Lazaret cave. The peptides and proteins present in the enamel were directly extracted at the surface of the teeth. The proteins were then digested with trypsin or chymotrypsin and analysed by LC-MS/MS. The results obtained show that the enamelin, COL1A3 and alpha-2-glycoprotein allow for taxonomic differentiation between Bos and Bison, while AMELX/Y sequences of the same samples allow for sex identification. Both were successfully performed on the 160-120 ky archaeological teeth, without affecting the specimen. This study highlights the potential of proteomics for simultaneous taxonomic and sex determination for others fossil samples, including rare or precious material, using low-invasive high-resolution mass spectrometry. It opens up unprecedent avenues for palaeobiological studies as well as cultural and natural heritage, and will widely participate to strengthen our knowledge of past animal and human communities. Such multi-proxy approach, shall be now developed for other mammalian species.

Palaeoproteomic analysis of a second hominin specimen from Baishiya Karst Cave, China

Project description:An archaeological bone fragment from Baishiya Karst Cave, China, was identified as stemming from a hominin through ZooMS (Zooarchaeology by Mass Spectrometry). Shotgun palaeoproteomic analyses were thereafter conducted on the specimen to refine the taxonomic identification and perform phylogenetic analyses. The reconstruted proteome shows that the newly described Baishiya Karst Cave individual, Xiahe 2, is most closely related to the high-coverage published genome from a Denisovan individual.

Assessment of seven minimally sampling protocols of archaeological skeletal proteomes

Project description:Archaeological bone material is increasingly being sampled for various molecular analyses. Minimally invasive sampling protocols should therefore be utilised whenever possible. We compare the proteomic output of 10 Early Neolithic Bos sp. humeri, from two different preservation contexts, of seven sampling protocols, namely retrieving bone chips (with and without demineralisation), acid etching (FASP and chemical neutralisation), eraser, membrane box, and polishing film. We note that minimally invasive sampling methods can extract a substantial amount of protein groups and provide sufficient taxonomic identifications if preservation conditions are favorable. However, if preservation conditions are poorer more invasive sampling techniques should be considered.

Ancient proteins extracted from ceramic residues

Project description:Ancient proteins were extracted from ceramic vessels from the West Mound of the key early farming site of Çatalhöyük, dating to the early 6th millennium BC. This analysis revealed that barley, wheat, pulses, as well as goat, sheep and bovinae dairy and meat products were contained in ceramic vessels. Moreover, this demonstrates that dietary proteins can be identified from archaeological artefacts from up to 6,000 BC and that this approach can unlock detailed evidence of past culinary practices, with more taxonomic and tissue-specific clarity than has been possible with previous biomolecular techniques.

Ancient DNA and protein preservation and transfer in concretions covering human remains

Project description:Archaeological remains covered with concretions, including human bones, are commonly found in certain areas and time periods of interest for understanding the past, but have yet to be investigated for potential ancient DNA (aDNA) and protein content. We extracted aDNA and proteins in tandem from human dental remains and the concretions surrounding them and compared them to non-concreted human dental remains from the same site. Concretions appeared homogeneous in colour and texture, consisting of a hard dark grey sediment adhered to the bone surfaces, presumably as a result of cyclical waterlogging of the burial deposits as well as postcranial human remains from a contemporary site. Concretions were found to contain human oral microbiome genomic and proteomic leached from the original skeletal source, as well as environmental and human proteins. Despite this, both the original element and concretions lacked endogenous human aDNA, indicating that the use of this type of material in future molecular archaeological applications is limited.

Low-invasive sampling method for taxonomic for the identification of archaeological and paleontological bone by proteomics of their collagens

Project description:Bone collagen is an important organic material for isotopic measurement, radiocarbon and paleoproteomic analyzes, to provide information on diet, dating, taxonomic identification. Current paleoproteomics methods are destructive and require from a few milligrams to several tenths of milligrams of bone for analysis. In many cultures, bones are raw materials for artefact which are conserved in museum which hampers to damage these precious objects during sampling. Here, we describe a minimal sampling method that identifies collagen, taxonomy and post-translational modifications from Holocene and Upper Pleistocene bones dated to 130,000 and 5,000 years ago using dermatological skin tape-discs for sampling. The sampled bone micro-powder were digested following our highly optimized eFASP protocol, then analyzed by MALDI FTICR MS and LC-MS/MS for identifying the genus taxa of the bones. We show that this low-invasive sampling does not deteriorate the bones and achieves results similar to those obtained by destructive sampling. Moreover, this sampling method can be performed at archaeological sites or in museums.
