This is a review of ‘‘The Toarcian Oceanic Anoxic Event in the South Iberian Palaeomargin’’ edited by Reolid, Molina, Nieto, and Rodriguez-Tovar (2018). The special publications, SpringerBriefs in Earth Sciences, are always a pleasure to read and this beautifully-produced book is a delight for researchers interested in the study of major biological and environmental crises. The book deals with one of the most important events of the Lower Jurassic, the Toarcian Oceanic Anoxic Event (T-OAE) which is documented in Jurassic outcrops of the Chain of the Betic Range (Reolid et al. 2018). On over 100 pages, the authors illustrate a very important area of Spain from a geological, palaeontological, and stratigraphical point of view. The technical details of the work are as follows: the organization of the volume is clear and subdivided into five chapters, each of them with their own reference list. The bibliography is abundant (263 titles) and the book contains fifty-two excellent illustrations, which are very useful, accurate, and often colorful. The first chapter introduces the reader to the state of art about the main topic of the volume: the boundary between the Pliensbachian and Toarcian stages and the Toarcian Anoxic Event. The second chapter shows the geological constraints of the Betic chain in both the Subbetic and Prebetic domains. A description of several stratigraphic sections of the Subbetic domain is given. The discussion about the Spanish Toarcian events covers two sections of the Subbetics: a median and an external one, in a setting of PCP (Pelagic Carbonate Platform, sensu Santantonio 1994) palaeogeographic evolution of a rift margin of the Mediterranean Tethys. Moreover, a biostratigraphic correlation based on ammonites is given, which have been found in all of the studied outcrops and their presence permits to correlate the outcrops with coeval ones in the Mediterranean–Tethys domain (Cecca et al. 1991). The median section is characterized by a basin-type succession on a deep area of the pelagic platform, where the stratigraphic sequence is thicker and the sediments are often reworked. The external section is characterized by a so-called high structure, a portion of the shallower pelagic platforms on which the succession is less thick and often lacunose. The third and fourth chapters describe in detail about the important outcrops and sequences that compose the studied sections, describing their stratigraphy, lithology, geochemistry, and palaeontology.
