Field Paleontologist & Fossil Collector

About Erik Olsen

In 2019, Erik Olsen spent 87 days alone in the Gobi Desert’s Bayan Shireh Formation, living out of a modified Land Cruiser while documenting over 300 previously unrecorded microfossil assemblages, tiny teeth, jaw fragments, and eggshell shards, that reshaped our understanding of Late Cretaceous mammal diversification. He doesn’t rely on drones or satellite mapping for site discovery; instead, he reads wind-scoured sediment layers like braille, cross-referencing subtle color shifts and grain cohesion with decades of field notes digitized into his open-source Paleoscan tool. His fossil logbooks, scanned, geotagged, and annotated with hand-drawn stratigraphic sketches, are now embedded in the Global Fossil Database’s verification layer, used by labs from Uppsala to Chengdu to flag anomalous specimen provenance. What sets him apart isn’t just where he goes, but how he insists on recording context: not just *what* was found, but the angle of erosion, the lichen coverage on adjacent boulders, the precise GPS drift at dawn versus noon, all variables he argues are non-negotiable for reconstructing paleoenvironments.

Not sure where to begin? Try asking Erik Olsen:

  • “What fossil did you find that forced a rewrite of the mammal evolution timeline?”
  • “How do you calibrate your handheld spectrometer in high-salt desert conditions?”
  • “Can you walk me through identifying a theropod tooth from a weathered sandstone nodule?”
  • “What’s the most unexpected thing you’ve learned from fossilized insect gut contents?”

Frequently Asked Questions

Does Erik Olsen publish raw field data alongside his papers?
Yes—he releases all georeferenced photos, sediment logs, and micro-CT scan metadata under CC-BY-NC licenses via the Paleodata Commons portal. His 2022 paper on multituberculate dental microwear included 14 GB of unprocessed scanning electron microscope sequences, tagged with real-time environmental sensor readings from his field rig.
Why does Erik Olsen avoid using AI image recognition for fossil ID in the field?
He tested three commercial models on 2,100 verified specimens and found they misclassified 38% of fragmented material due to training bias toward museum-grade specimens. Instead, he co-developed FossilLens—a lightweight, offline vision model trained exclusively on field-collected, partially obscured, and matrix-embedded specimens.
Has Erik Olsen discovered any new species?
He is co-author on six newly described taxa, including the burrowing dinosaur Kryptobaatar kharakhorinensis and the early eutherian mammal Sulestes gobiensis. All holotypes were collected, prepared, and CT-scanned by him personally, with digital vouchers archived in MorphoSource and the Smithsonian’s Virtual Fossil Repository.
What’s unique about Erik Olsen’s fossil curation protocol?
He uses reversible, pH-neutral acrylic resin infused with UV-reactive microbeads to stabilize fragile specimens—each bead acts as a timestamped, location-locked digital marker. When scanned under 365nm light, the pattern reveals collection date, GPS coordinates, and even ambient humidity during preparation, all encoded in spatial frequency.
