The systematic affinities and palaeoecology of P. wrangeli remained questionable. Here, the available specimens of P. wrangeli have been reexamined using scanning electron microscopy and x-ray computed tomography (microCT). Additionally, the elemental composition of the skeletal elements has been checked using energy dispersive X-ray spectroscopy. The resulting 2D-, and 3D-scans reveal that P. wrangeli consists of an alternation of distinct calcium phosphate (apatite) lamellae and originally organic-rich interlayers. The lamellae form four semicircular marginal pillars, which are connected by irregularly spaced transverse diaphragms. Marginally, the diaphragms and pillar lamellae are not connected to each other and thus do not form a closed periderm structure. A non-mineralized or poorly mineralized external periderm existed originally in P. wrangeli but is only rarely and fragmentary preserved. P. wrangeli often co-occurs with conulariids in fossil-rich limestone with mudstone–wackestone lithologies. Based on the new data, P. wrangeli can be best interpreted as a poorly mineralized conulariinid from an original soft bottom habitat.

abstract = {In this study we recognize complex physical biotic-abiotic interactions on a steep forested slope in the moderately elevated mountain terrain of the Sudetes, Central Europe, using geomorphological, pedological, and dendrochronological methods. On the forested hillslopes of Mt Rogowa Kopa the evidence of disturbance in natural systems is widespread. In the geomorphic subsystem its most obvious manifestation is the origin and disappearance of pit-and-mound microtopography resulting from tree uprooting. 82 pit-and-mound associations have been mapped on a test slope, providing quantitative data for calculating sediment flux. The flux is around 2×10-4m3m-1year-1, hence less than suggested in the literature but within the same order of magnitude. Nevertheless, in the long term such a transport rate is comparable with the one typical for creep, while it affects a greater thickness of hillslope regolith. Tree bending and abrupt changes in tree ring width are indicators of disturbed tree growth, causally linked to soil creep of mudstone-derived regolith. Eccentric growth is best recorded in wet years and in younger trees, which have to adapt to the pre-existing pit-and-mound surface topography. We offer a conceptual model that links biotic and abiotic factors and discuss implications of the widespread tree uprooting. We suggest that veneers of angular clasts and occasional larger boulders are not necessarily residuals of washed Pleistocene solifluction mantles but may result from root plate degradation after uprooting. Recent catastrophic wind events may, through tree uprooting, lead to structural changes in cover deposits so that they lose their inherited, periglacial signatures. © 2013 Elsevier B.V.},
