New records of the hypercalcified sponge Plectroninia (Calcarea,Minchinellidae) in the Recent deep ocean

Vacelet, J., James, B. 1, & Zibrowius, H., November 2017. New records of the hypercalcified sponge Plectroninia (Calcarea, Minchinellidae) in the Recent deep ocean. Alcheringa 42, 312–319. ISSN 0311-5518

Numerous small specimens of hypercalcified sponges of the genus Plectroninia (Jurassic to Recent) are recorded from deep water in the Atlantic, Indian and Pacific oceans, where they are attached to diverse hard substrata, mostly scleractinian skeletons. Being represented as skeletons of linked calcareous tetractines with an incomplete free spicule complement, the specimens could not be identified at the species level. These observations show that Plectroninia spp. have a wide distribution in the bathyal zone of the Recent World Ocean, where they may be the most common calcareous sponges.

Isotopic Evidence for Camelid Husbandry During the Formative Period at the Pacopampa Site,Peru

ABSTRACT

Camelids were domesticated in the Andean highlands, such as in the puna habitat, and dispersed into lowland areas and the northern Central Andes. As camelids domesticated in a particular region would have had a greater economic benefit than visiting- or hunted wild camelids, it is important to reconstruct the dispersal of camelid husbandry from its initial site throughout the ancient Andean civilisation. We carried out multi-isotope analyses of animal remains recovered from the Pacopampa site to investigate the nature of camelid pastoralism and utilisation. Strontium and oxygen isotope ratios from tooth enamel suggested that camelids in the early Late Formative Period (800–500 BC) were born near the site and remained in the same habitat for up to three years. Although corresponding data for the Middle Formative Period (1200–800 BC) were not available, carbon and nitrogen isotope ratios were statistically different from those of the Late Formative Period, supporting the possibility that the camelids inhabited the highland plateau like puna. It is inferred that in the northern highlands camelids were initially rare and regarded as either tribute or ritual animals, or they were used as pack animals. Camelid husbandry using maize as fodder began during the Late Formative Period at Pacopampa.
