Desde el ano 2005 el Laboratorio de Paleobiologia del Instituto Andaluz del Patrimonio Historico viene realizando estudios bioestratinomicos en las playas andaluzas ("El Espigon" en Huelva y "La Sardina" en Cadiz) que estan siendo utilizados en el conocimiento de la tanatobiodiversidad y en la dinamica de formacion de concheros actuales. La inferencia de los resultados obtenidos nos ha llevado a plantearnos el origen natural de algunas acumulaciones malacologicas en los yacimientos situados en la actual linea de costa; dos de los casos estudiados son los yacimientos romanos de "El Eucaliptal" (Punta Umbria, Huelva) y el "Cerro del Trigo" (Reserva Biologica de Donana, Almonte, Huelva). En ambos hallamos depositos malacologicos compuestos por unas 20 especies con individuos de talla superior al tamano minimo de consumo actual (establecido por la Consejeria de Agricultura y Pesca de la Junta de Andalucia), unas caracteristicas que encontramos en la malacotanatocenosis de las zonas de tormenta de la actual playa de "El Espigon". Como consecuencia de estos estudios, consideramos que la inferencia de los resultados bioestratinomicos en la interpretacion de los depositos malacologicos procedentes de excavaciones arqueologicas debe convertirse en una practica habitual siempre que sea posible, ya que aporta un conjunto de criterios cientificos que refuerzan la interpretacion paleoecologica, etologica e historica de dichos yacimientos.

UTM 28 R 590819 m E 3156129 m N, 15 m asl. The level is composed of cemented biogenic sandstones with basaltic boulders, approximately 1 m thick. Tortonian dating, defined by the gastropod association described above. The paratypes are from Playa del Valle and Barranco del Cuervito, both in Fuerteventura. <b>Etymology.</b> The species name derives from <i>Maham</i>, name of the subbmarine edifice common to the modern islands Lanzarote and Fuerteventura. <b>Description.</b> Shell small (Lmax: 40.6 mm; Wmax: 29.4 mm; Hmax: 15.6 mm), slightly conical, longer than wide. Fragile apex, present in a single shell (although severely worn away), situated further towards anterior region. Very fluted sculpture (between 25 and 30 ribs) starting from the very apex, with three slightly pronounced ribs in the posterior region. Deep narrow flutes divide these ribs. All grooves display concentrically arranged nodules or scales. Growth lines barely visible. In ventral view, the shell profile is quadrangular and sinuous in contour. The mantle edge of the studied specimens leaves no impression. <b>Remarks.</b> The shell of <i>P. mahamensis</i> <b>sp. nov.</b> is very similar to that of <i>P. intermedia</i> Murray, 1857 <i>in</i> Knapp, although the latter has a more rounded profile.

Figure 7 G, H, I <b>Type material.</b> Holotype: complete small sized adult specimen, poorly conserved (H: 23.3 mm; W: 17.8 mm), record number TFMCFO-6532/8. Paratype: three adult samples recorded as TFMCFO-6532/5 (H: 20.6 mm; W: 16.3 mm); TFMCFO-6602 (H: 14.9 mm; W: 12.9 mm); TFMCFO-3 420 (H: 23.1 mm; W: 19.4 mm). Other material examined. Another specimen from Lanzarote (TFMCFO-6602, Barranco de las Pilas) and 18 more from Fuerteventura (TFMCFO-3420, Morrete de los Castrillos; TFMCFO-3760, TFMCFO-6532, TFMCFO- 6583, Aljibe de la Cueva). Table 4 shows the biometrics and statistics for <i>Jujubinus ajachaensis</i> <b>nov. sp.</b> <b>Type locality.</b> Aljibe de la Cueva (Fuerteventura, Canary Islands). UTM 28 R 596484 m E 3171257 m N, 12– 17 m asl. The level is composed of coarse, loose biogenic sandstones, from 30 to 70 cm thick. Tortonian dating defined by the gastropod association described above. The paratypes are from Aljibe de la Cueva and Morrete de los Castrillos in Fuerteventura, and Barranco de Las Pilas in Lanzarote. <b>Etymology.</b> The specific name is derived from Los Ajaches mountains, in the south of Lanzarote. <b>Description.</b> Shell small (Hmax: 24.8 mm; Wmax: 10.4 mm), trochiform, fragile, with a high conical spiral, and higher than wide. Protoconch not observed in the studied specimens. Teleoconch composed of four whorls with a rounded profile, suture straight and moderately deep. Superficial sculpture nonexistent in adult individuals, except for fine folds in the last whorl that follow the direction of the fine, prosocyrt growth lines. Base slightly concave, with subquadrangular, holostomatous aperture. Lip not thickened. Some shells show an almost vestigial navel. <b>Remarks.</b> This new <i>Jujubinus</i> species is unlike any of the extant species distributed over the Canary Islands and their vicinity, which are of smaller size and display spiral cords throughout the shell. However, it is very similar to <i>Jujubinus [...]

Figure 5 G, H, I 1976 <i>Patella</i> cf. <i>intermedia</i> (Jeffreys). Meco: pp. 78,83. <b>Type material.</b> Holotype: Medium-size adult specimen with broken apex (L: 34.7 mm; W: 25.1 mm; H: 11.5 mm), record number TFMCFO-4605. Paratypes: Four samples, two of them very well conserved, with record numbers TFMCFO-4602 (L: 22.2 mm; W: 17.3 mm; H: 9.7 mm); TFMCFO-4 606 (L: 32 mm; W: 21.8; H: 13.2 mm); TFMCFO-4606b (L: 40.6 mm; W: 29.4 mm; H: 15.6 mm); TFMCFO-3527 (L: 22 mm; W: 14.9; H: 8.1 mm). <b>Type locality.</b> Barranquillos Blancos (Fuerteventura, Canary Islands). UTM 28 R 590819 m E 3156129 m N, 15 m asl. The level is composed of cemented biogenic sandstones with basaltic boulders, approximately 1 m thick. Tortonian dating, defined by the gastropod association described above. The paratypes are from Playa del Valle and Barranco del Cuervito, both in Fuerteventura. <b>Etymology.</b> The species name derives from <i>Maham</i>, name of the subbmarine edifice common to the modern islands Lanzarote and Fuerteventura. <b>Description.</b> Shell small (Lmax: 40.6 mm; Wmax: 29.4 mm; Hmax: 15.6 mm), slightly conical, longer than wide. Fragile apex, present in a single shell (although severely worn away), situated further towards anterior region. Very fluted sculpture (between 25 and 30 ribs) starting from the very apex, with three slightly pronounced ribs in the posterior region. Deep narrow flutes divide these ribs. All grooves display concentrically arranged nodules or scales. Growth lines barely visible. In ventral view, the shell profile is quadrangular and sinuous in contour. The mantle edge of the studied specimens leaves no impression. <b>Remarks.</b> The shell of <i>P. mahamensis</i> <b>sp. nov.</b> is very similar to that of <i>P. intermedia</i> Murray, 1857 <i>in</i> Knapp, although the latter has a more rounded profile. Its radial ribs are more numerous and more evenly thick. However, in the fossil species <i>P. mahamensis</i> <b>sp. nov.</b> from the Canary [...]
