Four Spiders in Baltic Amber Fossil–Lithuania Eocene

Multi-Spider Inclusion in Baltic Amber

Origin: Baltic Region (Lithuania) Geological Age: Eocene Epoch (approx. 40 million years ago)

1.6 cm x 1.5 cm x 0.5 cm;  0.7 grams

Description: This remarkable specimen of Baltic amber contains a stunning four-spider inclusion, an extraordinary example of mass entrapment from the ancient Eocene resin forests of Lithuania. Rather than a solitary creature, this piece preserves a cluster of arachnids caught together—offering rare insight into the social or aggregative behavior of prehistoric spiders and the sudden events that sealed them in place.

Each spider is preserved with exceptional three-dimensional detail. The fine body hairs (setae), segmentation of the legs, and even the delicate chelicerae remain visible through the warm, translucent golden matrix of the succinite. The reddish-amber tones beautifully contrast against the pale internal inclusions, giving the creatures an almost lifelike presence after more than 40 million years.

Multi-specimen pieces of this caliber are highly prized by collectors and researchers alike, as group inclusions are exponentially rarer than single-creature specimens and often indicate a rapid flow of resin over a nest or communal site.

Key Features:

Four Complete Spiders: A rare multi-inclusion specimen with all four arachnids largely intact.
Exceptional Detail: Visible setae, leg joints, and body segments preserved in crisp relief.
Behavioral Significance: Group entrapment hints at nesting or aggregation behavior in Eocene araneofauna.
Premium Baltic Succinite: Clear, honey-toned Lithuanian amber with natural surface texture.
