Silicified stem from the Late Eocene fossil locality of Kučlín (Czech Republic): overview and new remarks

Abstrakt

The silicified stem from Kučlín was first attributed to Podocarpoxylon helmstedtianum and linked with the co-occurring remains of Doliostrobus. Later it was re-interpreted as Tetraclinoxylon vulcanense and associated with twigs and seeds of Tetraclinis.

The new anatomical comparison reveals that exact botanical affinities of the silicified stem cannot be unequivocally established, mainly with respect to poorly preserved cross-field pitting.
