Experimental data of geoplate bedload signal of single pebbles
<p>Geophone raw data acquired during experiments carried out in the Hydraulics Laboratory of the Department of Civil, Environmental and Mechanical Engineering, University of Trento, Italy in dry and flow conditions.</p> <p>Experiments in dry conditions used a metal sphere hitting different locations on the plate. Signal was sampled with two different acquisition rates (10 and 30 kHz)</p> <p>Experiments in water flow conditions used 17 pebbles of different size and shape and 5 different flow conditions (F1 to F5).</p> <p>File "Metadata.txt" reports more information on how to read and use the dataset.</p> <p>These data have been used in the publication "Analysis of the vibration modes of impact geoplates and implications for bedload flux and grainsize measurements" by Portogallo et al., submitted to Water Resources Research.</p>

Figure 3 in The Paleocene cephalopod fauna from Pebble Point, Victoria (Australia) - fulcrum between two Eras
Figure 3. Aturoidea distans from Pebble Point, Victoria. Upper: small specimen NMV P 302005, showing the sutural morphology at shell diameter of 30-40 mm. Scale bar = 10 mm. Bottom: large specimen (not curated) in the Tate Museum, University of Adelaide, also from Pebble Point. One of the major differences compared to Aturia is the distance between septa. In both small and large (late stage) phragmocones, there is no contact between lobes. Scale bar = 5 mm.
Figure 4. Large Aturoidea distans from Pebble Point, NMV P326476 in The Paleocene cephalopod fauna from Pebble Point, Victoria (Australia) - fulcrum between two Eras
Figure 4. Large Aturoidea distans from Pebble Point, NMV P326476. Note also the corals growing on the shell, which could not have grown in this fashion during life of the nautilid. The corals are assumed here to have attached on the shell after the death, transport, and then final resting of the nautilid on a seabed shallower than the nautilid's life and growth habitat. However, these could not have grown in a high sedimentation rate environment. Scale bar = 10 mm.

Figure 8 in The Paleocene cephalopod fauna from Pebble Point, Victoria (Australia) - fulcrum between two Eras
Figure 8. Hypothesized generic level phylogeny of a portion of post-Jurassic nautilids. Eutrephoceras spp predate Nautilus and were not involved in subsequent generic evolution. Nautilus appears in either the Late Jurassic or Early Cretaceous, based on unpublished observations of P. Ward in the British Museum, and gives rise to subsequent genera Cimomia, Hercoglossa, Aturoidea, Aturia, and Deltoidonautilus. Nautilus also gives rise to Allonautilus in either Pliocene or Pleistocene.

Selectivity values greater than or equal to 1.0, indicated by the red dashed line (including 95% CI) indicate positive selection by M. leiaspis toward a given category, while values less than 1.0 (including 95% CI) indicate negative selection.

Small, cross-inscribed pebble
Culture: [Neolithic](http://n2t.net/ark:/99152/p0kh9dsbz2g) Material: Stone Dims: L 7cm Accession No: HCA 195 Current Location: [The Hunt Museum](https://www.huntmuseum.com/), Limerick. From Freugh, [Stranraer](http://www.geonames.org/2636719/stranraer.html), Scotland a small ovoid stone decorated with an oval frame, inscribed cross and a central, deep cut circular depression. Pebbles with various cross forms are found across Ireland and in smaller numbers in Scotland. Names given in modern times include altar, prayer, cursing ,priest's, pilgrim's and turning stones. The cross gives a religious feel but portable pestles, grinding stones and hammerstones date from the introduction of stone ground technology in the Neolithic.
