What was found
Researchers described Balticolasma wunderlichi from two Eocene amber fossils: a male preserved in Baltic amber and a likely conspecific female from Rovno amber in northwestern Ukraine. The specimens are roughly 34–38 million years old.
The discovery represents the first known fossil member of Ortholasmatinae, a harvestman subfamily with no living representatives in Europe today.
What makes that interesting
Synchrotron-based imaging allowed the researchers to examine the fossils' three-dimensional morphology in unusually fine detail. The combination of characters may place the animal near the ancestral lineage of living ortholasmatines, although its precise relationship remains open to further study.
Why it matters
A first fossil record does more than add an extinct name. It changes the known age and former distribution of an entire lineage, and gives researchers a new point of comparison for understanding how modern harvestman diversity developed.
