The oldest evidence of bioturbation on Earth: COMMENT
Recently, [Rogov et al. (2012)][1] discovered dense bioturbation fabrics, the preserved depth of which reached 5 cm, from the Ediacaran Khatyspyt Formation of the northern Siberian Platform. The age of the bioturbated beds is estimated at ca. 555 Ma. The ichnotaxon itself is attributed to the
150 years of the discovery of the Cambrian Lagerstätte of Murero (Cadenas Ibéricas, NE Spain).
The classical, lower and middle Cambrian Lagerstiitte of Murero (NE Spain) was first reported by the French geologist Edouard de Verneuil in 1862, and now it achieves 150 years of geological works. In this paper the main stratigraphical and palaeontological characteristics of the site are given. Murero is exceptional because the coexistence of both skeletal and soft - bodied groups along a continuous record of ca. 10 million years, which is subdivided into 14 trilobite biozones. The educational and social interest of the site is also highlighted.
150 años del descubrimiento del yacimiento cámbrico de Murero (Cadenas Ibéricas, NE España).
The lower-middle Cambrian palaeontological site of Murero (Cadenas Ibéricas, NE Spain) is a classical locality of the Cambrian in Europe. The site was first reported by the French geologist Edouard de Verneuil in 1862, and now it achieves 150 years of geological works contributing to a better knowledge of the Cambrian Period. Murero is an exceptional Lagerstätte because the coexistence of both skeletal and soft-bodied groups along a continuous record of ca. 8 million years, which is subdivided into 14 trilobite zones. Murero was the first palaeontological site in Spain to obtain the highest protection figure (Bien de Interés Cultural, BIC) from the Spanish Administration in 1997. Since then…
