“…However, a study by Collins et al (2014) on barnacles of the Plio‐Pleistocene in East Anglia, in which 17 barnacle species, including Balanus crenatus , Balanus balanus and Chirona hameri , have been detected, did not find any A. improvisus . Similarly, for example, in prehistoric sites in caves in Northern Spain (23 000–3500 cal bp , Upper Pleistocene to Holocene), among seven species of barnacles including Semibalanus balanoides and Balanus crenatus , no A. improvisus was found (Carriol and Álvarez‐Fernández, 2015).…”

The bay barnacle Amphibalanus improvisus (Darwin, 1854) has been found in Northern Germany in brackish marine sediments of the Holsteinian interglacial. Whereas the cause of the contemporary distribution of this species is anthropogenic and there is evidence that it has resulted mainly from shipping, the fossil findings demonstrate that A. improvisus had also already reached Europe naturally during the Pleistocene in Europe, probably via the Gulf Stream system of the Atlantic. Today, A. improvisus is considered one of the most successful aquatic invasive species worldwide and it is characterized by a high environmental tolerance. The ingression of the Holsteinian Sea, during the Pleistocene, took place during the climate optimum from the North Sea into the ‘Elbe Estuary’ through the Hamburg region and far to the south‐east into Brandenburg. It has been possible to reconstruct the palaeo‐ecological conditions based in particular on molluscs. Accordingly, environmental conditions ranged from normal marine in the north, via brackish in the transitional area to limnic–fluviatile in the Berlin region. The morphological features of the bay barnacles and their ecological parameters are described here in detail. In addition, we provide a general review of the known Pleistocene Balanidae in northern central Europe.

“…nov. both the multitubiferous structure and the vesicular sheath, has an extremely limited fossil record consisting of a single occurrence from the upper Pleistocene of Atlantic Spain. However, it is noteworthy that the holotype of this enigmatic genus was found in a prehistoric site together with intertidal molluscs gathered by primitive humans (CARRIOL & ÁLVAREZ-FERNÁNDEZ 2015).…”

“…The observation of auxiliary septa that partition the parietal tubes also allows to distinguish Perumegabalanus calziai gen. et sp. nov. from the enigmatic balanid Titobustillobalanus(CARRIOL & ÁLVAREZ-FERNÁNDEZ 2015), whose assignment at the subfamily level is to date uncertain.…”

Living members of the tribe Austromegabalanini are large balanid barnacles (Crustacea: Cirripedia: Neobalanoformes) that live in temperate and cold waters of the Southern Hemisphere. During the Neogene, however, the austromegabalanines also inhabited the Northern Hemisphere, as well as some low- latitude tropical environments. This paper describes a new taxon of austromegab-alanines, Perumegabalanus calziai gen. et sp. nov., from the shallow-marine, nearshore, lower Miocene (19 to 17 Ma, Burdigalian) deposits of the Chilcatay Formation (East Pisco Basin, southern Peru). Among austromegabalanines, this new taxon is characterised by the presence of thick, ornamented, multitubiferous parietes, where the parietal tubes are irregularly partitioned by auxiliary sep - ta; in addition, the sheath is vesicular. Based on morphofunctional considerations, the peculiar shell architecture of P. calziai is here interpreted as well-suited for an existence in the intertidal zone. In the Chilcatay strata, two taxa of Austromegabalanini (i. e., Austromegabalanus carrioli and P. calziai) coexist, representing some of the geologically oldest records of austromegabalanines worldwide – an observation that strongly supports the hypothesis of a circum-equatorial origin and early diversification for this successful lineage of acorn barnacles.

“…However, this could change if the late Cainozoic balanomorph Titobustillobalanus tubutubulus from northern Spain is included in the genus. Unfortunately, key features of T. tubutubulus are unknown (Carriol & Álvarez-Fernández 2015). Nonetheless, as noted, there are differences in the arrangement of longitudinal parietal pores.…”

Revision of Southern Hemisphere taxa referred toFosterella(Crustacea: Cirripedia), and their extinction in response to Pleistocene cooling

Extensive barnacle coquinas (barnamols) formed around New Zealand's North and Chatham Islands during the late Pliocene to early Pleistocene. The inner-shelf megabalanine Fosterella is the primary constituent of these lithofacies, which also include epifaunal bivalves, bryozoans and less modified balanids like Notobalanus and Notomegabalanus. The status of genus Fosterella is reviewed, 3 species are retained and a new genus, Porobalanus, is proposed for Fosterella hennigi, a species restricted to the Early Pliocene of Cockburn Island, Antarctica. Significantly, Fosterella did not survive the New Zealand Pleistocene, although Notobalanus and Notomegabalanus, which have fossil records extending back to the Early Miocene, remain important components of present day cool-temperate Southern Hemisphere faunas. Extinction of Fosterella, in shelf waters off Argentina, is explained through a combination of changing circulatory and sedimentary regimes, competition for food and space, predation and physiological constraints. The driver of these factors was rapid regional cooling. Zoobank registration: urn:lsid:zoobank.org:pub:DBB1CB34-83E4-48BA-AA10-81823017F37A.
