Distribution:

The species is known only from the type specimen in Baltic amber of the Kaliningrad area. Following the Palaebiology Database (2020), this amber dates from the Priabonian period (38.0-33.9 Ma): "According to Aleksandrova and Zaporozhets (2008), the higher parts of the Prussian Formation (including the Blaue Erde or Blue Earth) belong to the Charlesdowniea clathrata angulosa dinocyst Zone. Based on its index species, this zone is concurrent to Zone W13 established in the Parisian basin (Châteauneuf and Gruas-Cavagnetto 1978), where it is correlated with nannoplankton zones NP18–NP21 (Powell, 1992) of the Priabonian. In the Paleogene zonation of northwestern Europe, the first occurrence of Thalassiphora fenestrata is designated at the base of the dinocyst Subzone D12b (36.20 +/- 0.1 Ma), which is correlated with zones NP18 (terminal part)–NP20 of the Priabonian (Luterbacher et al., 2004)."

The species is a member of the amber wood biocenosis. In a relatively warm period in the Eocene, the amber wood stretched from Scandinavia to the Ural Mountains in a broad belt. In the south, it was bordered by an ocean, which reached far into eastern Europe and Asia. The wood consisted of coniferous trees to some extent, mainly Pinus succinifera and ancestors of the extant genus Pseudolarix, similar plant associations being present also in North America and throughout temperate Asia (all information retrieved from wikipedia 2010). Gymnosperms and Angiosperms have been plentiful developed already in that wood (e.g. Goeppert & Menge 1883). The climate has been assumed to be mild and wet, the wood itself to be marshy.

Stages in development:

The early stages are unknown.
