Hepatics from Rovno amber (Ukraine). 11. Radula oblongifolia and R. tikhomirovae sp. nov.

Abstract

A study of Rovno amber has revealed two fossil leafy liverwort species of the genus Radula (Radulaceae, Marchantiophyta) that are new to the late Eocene flora of Rovno amber. One of these species, R. oblongifolia, was described previously from Eocene Baltic and Bitterfeld amber, whereas the other species, R. tikhomirovae, is described here as new. Radula tikhomirovae differs from R. oblongifolia and two other Eocene species of that genus, R. sphaerocarpoides and R. baltica, by the presence of microphyllous branches and by the shape of its leaf lobules.

The new species and two new records of Polycentropodidae (Insecta: Trichoptera) from Eocene Rovno amber

“…Specimen SIZK UA-28168 was collected in Rovno Region. Twelve arthropod and three plant species were reported from the amber, collected from Zhitomir Region, mostly from Olevsk (Melnitsky et al 2021b;Shamshev and Perkovsky 2022;Chemyreva et al 2024;Mamontov et al 2024aMamontov et al , 2024bMamontov et al , 2024c; 13th arthropod species was added in the present paper.…”
