A farewell to Świniary sequence of mass-aggregated, spine-coated echinoids Psammechinus and their associates (Middle Miocene; Holy Cross Mountains, Central Poland)

  title={A farewell to Świniary sequence of mass-aggregated, spine-coated echinoids Psammechinus and their associates (Middle Miocene; Holy Cross Mountains, Central Poland)},
  author={Andrzej B. Radwański and Anna Wysocka},
  journal={Acta Geologica Polonica},
The Świniary sand-pit (Middle Miocene; southern slopes of the Holy Cross Mountains, Central Poland), which has yielded innumerable fossils of various kinds over the last fifty years, is revisited. Most significant there were mass accumulation of a single echinoid species, Psammechinus dubius (L. AGASSIZ, 1840), tests of which preserved spine canopies and Aristotle's lanterns in position. Other echinoids represented were rare, e.g. Spatangus austriacus LAUBE, 1871, 'Giant Psammechinus sp…

The new species, the dorsal valves of which are characterized by their small size, low-conical to strongly and irregularly depressed shape, and by the distinct robbing, bears some similarities both to the species D. scutellum from the contemporaneous deposits of the Vienna Basin and to some Recent species typical on the Indo-Pacific realm.

The fossil genus Micraster from the Chalk gives an excellent example of continuous evolution of individual characters, but changes in the urchins probably reflect either a change in niche or an improvement in the adaptation of the animal in an effectively unchanged niche.

Lateral variations of size‐frequency distribution in a fossil echinoid community and their palaeoecological significance
The analysis of size-frequency spatial distribution of three species of Cenomanian echinoids in a single fossil assemblage shows both intraspecific and interspecific horizontal segregation of the individuals parallel to the variations in silt and organic matter levels of the substrate, suggesting that a catastrophic event resulted in the fossilization of the demographic structure of the populations.
