    Predatory behaviour on Ostracoda: spatial analysis of drill-hole distribution in relation to shell size and ornamentation onlinelibrary.wiley.com/doi/10.1111/pa… #FossilFriday @matias_ritter @datadryad
    Top left: map showing Valparaiso and Santiago (red diamonds) in Chile (shaded grey) and the study region outlined in red. To the right are two black and white photographs of drilled left valves of ostracods from the Miocene Navidad Formation. Upper image is Cytherella with drill hole trace Oichnus simplex; lower image is Apatihowella with hole trace O. paraboloides. Each photograph has a scale bar in the lower left corner, which is 100 microns.
Lower right plot is a frequency distribution for outer drill hole diameter (vertical axis), with trace O. paraboloides on the left, in red, and O. simplex on the right in blue.
Blue rectangle at the top in the centre is a cover image from the journal Palaeontology.

    At the top are two photographs of fossil octocorals, both species of Waiparaconus. On the left, a reddish fossil, W. imbricatus (MN-12294-I) from Vega Island off the Antarctic Peninsula (Snow Hill Island Formation). On the right, the holotype of W. gravidus (WAM 77.3532a) from Western Australia (Gingin Chalk). Scale bar beneath each image is 1 cm.
At the bottom is an artist's reconstruction of both species.

    A new fossil from the Eocene of Iran provides new insights regarding the evolution of the morphologically bizarre tube-eye fish onlinelibrary.wiley.com/doi/10.1002/sp… #PapersinPalaeontology @unito
    Main image is a photograph of an elongated fossil fish in a pale matrix, with the head in the lower right corner. This is the holotype of Parastylephorus anatoides (IUGM 100897) from the Eocene of Babaheydar (Iran). Scale bar at lower left is 10 mm.
Top right is a reconstruction of the head and anterior body of this tube-eye fish (green eye to the left). Artwork by Lucrezia Bonardo.
Red rectangle below the reconstruction is a cover image from the journal papers in palaeontology.
