Amber trees are coniferous trees from the pine family (pinaceae).

Their height reached 50 metres, while their width could be up to 1.5 metres.

Aside from median-climate trees the Fennoscandic forests also contained subtropical flora, while the forest fauna was especially rich in insects.

The warming climate meant that conifers expelled greater volumes of resin than usual, which gradually became a pathological phenomenon that determined the formation of amber.

The volumes of tree resin being extruded were in the end the cause of the amber trees' extinction.

Plant fragments found in amber testify to the climate from this time: some amber pieces contain remains of coniferous and deciduous trees (pines, cypresses, cedars, sequoias, thujas, oaks, bay trees, palms, almond trees, chestnut and beech).

Although floral plant inclusions are very rarely encountered, meadow grasses and wetland plants are sometimes found. Those species that were wind, not insect, pollinated predominate.

The oak blossom filaments are the distinguishing feature of Baltic amber.
