An Unusual Protuberant Lithophyllum sp. From Southern Spain Increases Structural Complexity in Urchin Barrens

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.
ABSTRACT Urchin barrens (‘blanquizales’) are habitats dominated by encrusting non‐geniculate coralline algae and maintained by urchin grazing. Taxonomic information of coralline communities in Mediterranean blanquizales is limited. Lumpy to fruticose coralline algal specimens, unusual in blanquizales, were found along the southern Spanish coast ...

Formation and preservation of vertebrate tracks in semi‐liquid sediments: Insights from tidal flats and laboratory experiments

open access: yesSedimentology, Volume 72, Issue 1, Page 5-33, January 2025.
ABSTRACT Despite the valuable palaeoecological and palaeoenvironmental information provided by vertebrate tracks, those made in semi‐liquid sediments have been largely overlooked because they are assumed to be preserved as a mass of disrupted sediment and to have a low preservation potential.
