Se citan las distintas leyes de las comunidades autónomas españolas y las del propio estado español referente a la protección del patrimonio paleontológico y se muestras dos ejemplos prácticos de tasaciones paleontológicas.

Aqui se acepta que alcanza el Cretacico y que incluye Ostrea pasiphae. Se recuerda la sinonimia de esta especie, descrita del Aptiense espanol (Provincia de Teruel). EnglishThe history of the genre Liostrea is remembered, whose chronostratigraphy is diverse according to the authors. Here it is accepted that it reaches the Cretaceous and that includes Ostrea pasiphae. The synonymy of Ostrea pasiphae, described from the Spanish Aptian (Province of Teruel), is also remembered. So the species must be called Liostrea pasiphae.

Tambien se describe los metodos conocidos para su correcta deteccion.

Con esta nueva especie y otra mas todavia por describir, el genero Platypeltoides cuenta en Marruecos con cuatro especies diferentes, todas ellas pertenecientes al Ordovicico Inferior (Tremadociense). EnglishIt is described a species of the genus Platypeltoides, P. carmenae, from the Fezouata shales, Lower Ordovician (Tremadocian) of the Guelmim province (Morocco). With this new species and another which is still pending to be described, the genus Platypeltoides includes four different species in Morocco, all them belonging to the Lower Ordovician (Tremadocian).

EnglishAll the techniques, tools and equipment used in preparing Moroccan trilobites and their evolution are presented here: From hammer and chisel to electric and pneumatic drills, steel needles and dental instruments, disc cutter and finally the air compressors.

This isopod is identified as Unusuropode castroi , is the first reference to this species outside of Brazil and also represents the first formal description of Unusuropode castroi in Africa. Gara is Sbâa, is located in the region of Kem Kem (southeast of Morocco) and is presented as a new locality for the isopod Unusuropode castroi , from the Upper Cretaceous (Cenomanian / Turonian), previously described only in the Turonian of the Apodi Group, Arenito Acu, state of Ceara Brazil. With this new isopod the statement of Martill et al . [1] is reinforced, indicating the affinities between the faunas of South America and Morocco during the Cretaceous. This document presents the two types of Unusuropode castroi differentiated by their size that also appea...

Una corresponde a la conocida especie albiense Nerinea capelloi, descrita por Choffat, 1888, que se incluye en Eunerinea. La otra se considera especie nueva y asi se describe. Se llama M ultiptyxis angolensis y proviene del Albiense. El genero amplia su distribucion paleogeografica. EnglishTwo species of Nerineacean gastropods are studied. The first one is the known albian species named by Choffat (1888) as Nerinea capelloi, which is included here in Eunerinea. M ultiptyxis angolensis is proposed as a new species and carnes also from albian beds. This genus enlarges its palaeogeography.

They are Ogyginus forteyi hammondi n. ssp.; Megistaspis (Ekeraspis) hammondi n. sp.; Megistaspis (Ekeraspis) hammondi forteyi n.ssp. and Basilicus (Basilicus) vidali n.sp. We will also show all the specimens of giasnt trilobites from Lower Ordovician of Morocco so far found, some already described by other authors, and other not desctibed yet.

Computed tomography of the holotype and paratype kept at the Natural History Museum in London (United Kingdom) for the conduct of a study on computed tomography and radiography as expert legal evidence in paleontology has revealed the hypotheses of the two previously cited specimens (Corbacho and Lopez-Soriano, 2012) and another disarticulated specimen below, which was discovered during the computed tomography process. All CT Scanning images in this article have been obtained from a CT Scanned at the Natural History Museum, London, UK. By describing the ventral aspect and the hypostomes of the specimens studied in this article, any possible uncertainty and affiliation to Nileidae is stated and dissipated as suggested by Gutierrez Marco, Sa, Garcia Bellido and Chacaltana as belonging to Asaphidae, incorrectly suggesting that It is the species: Asaphellus stubssi Fortey, 2009. Consequently, membership in the Nileidae family is reaffirmed and Asaphidae is ruled out. The genus Platypeltoides is also reaffirmed and Asaphellus is discarded. Being the correct species Platypeltoides cuervoae (Corbacho & Lopez-Soriano, 2012).
