Live from #IZAZ2024 at @CollegedeFrance - Karen Ruebens discussing integrating #ZooMS and #zooarchaeology research with organizers Giulia Gallo, Raija Heikkilä & Pauline Raymond. When and when will #IZAZ2026! #archaeology #biomolecular
A presentation slide titled 'Keratin and Keratin Associated Proteins (KAP/KRTAP) - A lot of variety' showing extensive lists of different keratin types and their associated genes on chromosomes 17 and 21. The slide details acidic and basic type I and II hair keratins. The presenter gestures while explaining this complex molecular information.
Now the camelids: arrgh keratin variation 🤪! Deep dive into keratin complexity at #IZAZ2024. This complexity is both a challenge and an opportunity for archaeological identification methods! #proteomics"
A presentation slide showing a series of labeled baleen whale artifacts (in yellow/gold coloring) alongside a map of Europe with coastal sites marked in red. The artifacts appear to be worked whale bone or baleen strips, each with a 'DAG' catalog number. The presenter, in a burgundy shirt, is gesturing while speaking.
A fascinating large piece of archaeological detective work: using ZooMS to identify whale species from worked artifacts across European coastal sites. Each specimen helps reconstruct historical whale populations and human-whale interactions! 🐋 #archaeology #IZAZ2024
Title slide showing 'ZooMS and Palaeoproteomics Analysis on two Charismatic Taxonomic Groups: Whales (Collagen) and South American Camelids (Keratin)' by Youri van den Hurk. The slide features an underwater image of a whale and an artistic illustration of an alpaca. The presenter stands at left in a burgundy shirt."
From ocean depths to Andean heights: fascinating methodological challenges in analyzing different protein types (collagen in whale bones, keratin in camelid textiles). Great example of adapting ZooMS methods to different archaeological materials! #IZAZ2024
A presentation slide titled 'Bird protein database' showing genomic data from the B10K project, including 160 genomes and 112 species in Anatidae (ducks, geese, swans). The slide features a phylogenetic tree and illustrations of bird proteins including collagen, ovotransferrin, and albumin. A citation to a 2024 Nature paper is visible.
The team is working with the🦆 bird @B10K_project database presented at #IZAZ2024: 160 genomes, including protein data for 112 species of ducks, geese and swans! This kind of comprehensive reference data is crucial for archaeological identifications.
A presentation slide showing 'Integrating ZooMS and zooarchaeology to improve the interpretive value of avian remains' by Maria Codlin, Lisa Yeomans, and Beatrice Demarchi. The slide features university logos and a colorful illustration of a landscape emerging from a cracked egg. Maria Codlin presents in a grey shirt, with another conference attendee visible in the foreground.
🦅 Switching from fish to birds at #IZAZ2024! Maria Codlin presenting on integrating #ZooMS with traditional zooarchaeology for better understanding of avian remains. Birds are challenging to ID morphologically, so this integration is crucial! Sorry for the blurry photo
A presentation slide titled 'GMM+AI+ZOOMS' shows scatter plots of geometric morphometric analysis, along with photos of four collaborators: Nidiyare Hevia, Jorge Perez, Ariana Solis, and Xavier Chiappa. The presenter is in the foreground discussing the integration of these methods.
🔬 The future is integrated! Exciting to see combination of Geometric Morphometrics (GMM) + AI + ZooMS for more robust species identification. The power of combining shape analysis with molecular methods 📊 #IZAZ2024
A presentation slide titled 'DNA BARCODING' shows two circular taxonomic diagrams (sunbursts) representing fish diversity. The text indicates analysis of 135 specimens across 22 families, 42 genera and 71 species, with a 5% misidentification rate. BOLD Systems logo appears in corner. The presenter stands at left.
Beautiful visualization of fish diversity to deposited in BOLD Systems at #IZAZ2024. These reference collections are crucial infrastructure for future archaeological work - and showing misidentification rates (5%) is important methodological transparency 🐠 #OpenScience
A presentation slide titled 'Reference Collections: Fishing for IDs' shows six photographs documenting the process of collecting fish specimens from markets and ports. Below are listed four methodological steps: anthropological approach, data recording, identifications, and skeletal preparation. The presenter stands at left beside a desk with a MacBook and microphones.
🎣 Love seeing the work of building reference collections at #IZAZ2024! Can you spot Philippe BÉAREZ working with local fishermen and markets; the team combines traditional knowledge with cutting-edge science. Real interdisciplinary archaeology in action!
A presentation title slide showing 'Establishing Taxonomic Accuracy in Ichthyoarchaeology: A DNA-Barcoded Collagen Reference Collection for Indo-Pacific Fish' with an image of colorful fish at a market or dock. The presenter, Nayeli Jiménez Cano, stands in a black sweater speaking into a microphone. The slide shows multiple institutional logos including the Muséum National d'Histoire Naturelle and CNRS.
☕️ Back from coffee at #IZAZ2024 for Nayeli Jiménez Cano's talk on creating reliable fish reference collections. Combining DNA barcoding with collagen analysis is crucial for accurate species identification in archaeological fish remains 🐟 #archaeology
A presentation title slide from the Max Planck Institute of Geoanthropology showing 'Fish in the Oasis: Zooarchaeological and ZooMS insights into fish exploitation along the Ancient Silk Road in Central Asia' by Carli Peters, Noel Amano, and Robert Spengler.

A presentation slide showing WWF infographics of six Danube sturgeon species: Beluga, Russian, Stellate, Ship, Sterlet, and European sturgeon. Each species is illustrated with conservation status indicators, most marked as 'critically endangered'. The presenter is visible at the bottom, speaking at a desk with a MacBook and microphone. A URL for danube-sturgeons.org is shown at the bottom of the slide.
Why this matters: Archaeological samples could help understand sturgeon population changes over centuries. ZooMS offers new ways to ID species in old collections, filling crucial gaps in our knowledge of these endangered fish. #conservation #IZAZ2024

A slide shows text 'Do not toss your empty tubes! You never know when they may become useful...' next to a box containing multiple labeled sample tubes arranged in a grid pattern.
🧪 Pro tip from #IZAZ2024: Keep those 'empty' tubes! Even trace amounts of collagen can yield valuable #ZooMS data. Every microliter counts! 🔬
A slide titled 'One scientist's trash is another scientist's treasure' shows three lab photos of gloved hands holding small tubes, with test results showing that 'empty' Falcon tubes and <30 kDa collagen samples both yielded 7-9 peptide markers.
💡 'One scientist's trash is another scientist's treasure' - Finding usable peptide markers in 'empty' tubes! Brilliant proof that #ZooMS can extract data from even trace amounts of collagen #IZAZ2024

A presentation slide titled "Assessing destructiveness" at the IZAZ 2024 conference. The slide displays several 3D-rendered images of archaeological bone specimens, from the La Draga site. The presenter, Jan Dekker, is explaining how these 3D imaging techniques can be used to assess the level of destructiveness caused by different sampling methods on the bone samples.
The value of 3D imaging demonstrated by Jan Dekker at #IZAZ2024 to evaluate the impact of various sampling protocols on the integrity of archaeological bone specimens.
