A bit of quantitative paleoecology
The Amateur Paleontologist posted a topic in General Fossil Discussion
Just got this new idea for a future MKFRP research avenue Basically, on the beach near the cliffs, there is this area filled with small bits of fossils washed out from the chalk (the so-called "washout zone"). I'll make a sampling of that area, with a few control variables included (i.e. sampling area, maximum sampling depth, fossil size class, quantity of fossils). The sampling will be done by scooping washout material with a bucket & spade, bringing it home and then picking out individual fossils. Based on the fossils collected, I'll then establish relative faunal abundances based on percentages of particular fossil groups. The results obtained from the data will hopefully help to further understanding of the paleoecology of Møns Klint. Similar research has been done on places like Stevns Klint or Rügen, so I'd be expecting similar results for Møns Klint. Small preliminary hypothesis: fish remains won't have reach an abundance higher than ~5% Closeup picture of the "washout material"; taken from Meyer (2015) - "Fossilerne fra Møns Klint"- 1 reply
