TL;DR: Coleoptera from three late-glacial sites on Cape Breton Island, Nova Scotia, Canada, provide proxy climate data from 12'600 to 10'400'BP.
Abstract: Coleoptera from three late-glacial sites on Cape Breton Island, Nova Scotia, Canada, provide proxy climate data from 12 600 to 10 400 BP. Samples older than about 11 800 BP contain tundra to tree-l...

TL;DR: Palaeoentomological interpretations from buried organic sites near Joggins, Lantz and Blomidon are consistent with palynological results from the region and support evidence derived from lake sediments for regional steep climatic gradients during the late-glacial period in the Maritimes as mentioned in this paper.
Abstract: Three late-glacial sites in central Nova Scotia, Canada, have produced small Coleoptera assemblages that add to the palaeoenvironmental interpretation during the interval 11,800 to 10,800 years B.P. in the Maritimes region. During this time, beetle assemblages are boreal in nature, in contrast to older sites which contain tundra to tree-line species and later, Younger Dryas age sites, containing northern boreo-montane species. Palaeoentomological interpretations from buried organic sites near Joggins, Lantz and Blomidon are consistent with palynological results from the region and support evidence derived from lake sediments for regional steep climatic gradients during the late-glacial period in the Maritimes. RESUME Trois emplacements tardiglaciaires du centre de la Nouvelle-Ecosse, au Canada, ont produit des assemblages de petits coleopteres qui ajoutent a l’interpretation du contexte paleoenvironnemental existant pendant l'intervalle de 11 800 a 10 800 ans BP dans la region des Maritimes. Au cours de cette periode, les assemblages de coleopteres presents etaient de nature boreale, par contraste avec les emplacements plus anciens abritant des vegetaux variant de la toundra a la limite de vegetation des arbres, ainsi qu'avec les sites plus regents de l'epoque des dryades ulterieurs renfermant des especes boreales subalpines septentrionales. Les interpretations paleoentomologiques des emplacements organiques enfouis pres de Joggins, Lantz et Blomidon correspondent aux constatations palynologiques de la region et appuient les indications tirees des sediments lacustres temoignant de gradients climatiques regionaux eleves pendant la periode tardiglaciaire dans les Maritimes.

TL;DR: A late-glacial shell fauna from Point Lepreau, New Brunswick produced a radiocarbon date of 13,500 years B.P. The assemblage contained well-preserved subarctic to boreal molluscs and barnacles typical of late Pleistocene marine deposits from the region.
Abstract: A late-glacial shell fauna from Point Lepreau, New Brunswick produced a radiocarbon date of 13,500 years B.P. The assemblage contained well-preserved subarctic to boreal molluscs and barnacles typical of late Pleistocene marine deposits from the region. Rare specimens of sea urchin, crab and brittlestar may be the oldest recorded occurrence of these animals in the late-glacial Bay of Fundy. The assemblage fits into a previously defined Zone 3, late-glacial marine invertebrate assemblage in the Bay of Fundy-Gulf of Maine region, characterized as a Diverse Arctic assemblage. RESUME La datation par le radiocarbone a situe a 13 500 ans BP une faune invertebeie tardiglaciaire de la pointe Lepreau, ou Nouveau-Brunswick. L'assemblage renferme des mollusques et des bernacles subarctiques a boreaux bien conserves caracteristiques des depots marins du Pleistocene tardif de la region. Les specimens rares d'oursins, de crabes et d'ophiures pourraient constituer les manifestations les plus anciennes de la presence de ces animaux relevees dans la region tardiglaciaire de la baie de Fundy. L'assemblage se situe a l’interieur de l'assemblage d'invertebres marins tardiglaciaires de la zone 3 anterieurement defini dans la region de la baie de Fundy et du golfe du Maine, caracterise en tant qu'assemblage arctique heteiogene.

TL;DR: Since publication of the New Brunswick Museum's first catalogue of type fossils in 1988, over 240 specimen records have been added to the collection of primary and secondary types, including invertebrates, ichnofossils and vertebrates as mentioned in this paper.
Abstract: Since publication of the New Brunswick Museum's first catalogue of type fossils in 1988, over 240 specimen records have been added to the collection of primary and secondary types. The list includes fossils recovered from the collection of G.F. Matthew that are considered to have type, or probable type, status. New specimens resulting from publications since 1988 include invertebrates, ichnofossils and vertebrates. RESUME Depuis la publication du premier catalogue de fossiles stratigraphiques du Musle du Nouveau-Brunswick en 1988, on a ajoute plus de 240 enregistrements de specimens a la collection de types primaires et secondaires. La liste englobe des fossiles provenant de la collection de G.F. Matthews, consideres comme des fossiles de types definis ou de types et valeurs probables. Les nouveaux specimens decoulant des communications publiees depuis 1988 comprennent des invertebres, des ichnofossiles et des vertebres. [Traduit par la redaction]
