Despite the long and celebrated research record of palaeontology at Leicester, the School of GGE is being affected by significant redundancies. What this means for PGRs is still uncertain, and we urge the University leadership to provide guidance and contingencies to help support (continue)

The Palaeontological Association has written to the President of the University of Leicester, requesting that the concerns of the PhD community over the planned redundancy of their supervisors are addressed.

Top left: Map of Chile and Argentina with the study location indicated in red. Top right: two thin section photographs showing internal structures within new wood species Sahnioxylon chubutensis (MPEF-Pb 13152): on the left a general view of the pith and primary and secondary xylem (scale bar 500 microns); on the right tracheids with scalariform and araucarian pits (scale bar 100 microns). At the bottom, a photograph showing two growth rings within Sahnioxylon and plots to the right showing cumulative sum of deviation from the mean radial tracheid diameter for those rings. On the plots, the proportions of earlywood and latewood correspond to yellow and red shaded areas respectively. Bottom right corner: cover image for journal Papers in Palaeontology.

Main image is a reconstruction of extinct fish Gondwanacanthus decollatus swimming in its natural environment. On the left are two photographs of fossil specimens: at the top, the holotype (MCP2457) which preserves vertebrae, ribs, rays and fines of the main body and tail; at the bottom, paratype MCP3458D, which preserves large spinoid scales in several rows, with the lateral line running horzontally across the centre. Small red image in lower right corner is the cover of Papers in Palaeontology, the journal in which the new species is described.

Bottom: scanning electron micrograph of a sclerite bearing vesicular microfossils of possible fungus or bacterium Avannacystis polaris. A white arrow near the top indicates a slightly embedded specimen, and a white arrowhead at bottom left shows a specimen with invagination, a feature that has been interpreted as indicating a biological origin for these protuberances.
