Dr. Mantell, in his classical work, the “Fossils of the South Downs,” figured two large compressed and lanciform teeth preserved in his collection and obtained from the Chalk at Lewes, as respectively the teeth, of an unknown fish and of a species of Squalus. Similar teeth, and from the same collection, were subsequently figured and described by Prof. Louis Agassiz, who, from external characters chiefly, considered them to have belonged to a Sphyrænoid fish, and he referred them to an American species founded by Dr. Harlan upon portions of jaws with teeth in situ found in a Cretaceous deposit in the State of New Jersey, but described by him as remains of a Saurian, and to which he gave the name of Saurocephalus lanciformis. At the time when Agassiz referred these teeth to Harlan's species, and determined their ichthyic character, he had not seen the American fossils; but he states that these conclusions were subsequently confirmed by Prof. Owen's description and drawings of the microscopic structure, and of teeth of the natural size of the Saurocephalus lanciformis, Harl., in his “Odontography,” p. 130, pl. 55. But Prof. Owen's researches were made upon a genuine tooth of the American fossil sent to him by Dr. Harlan, and not upon an English specimen.

AbstractBostwickite, CaMn63+Si3O16-7H2O, is a new species from the Franklin Mine, Franklin, New Jersey. Chemical analysis yielded MgO 0.9, CaO 5.1, Mn2O3 56.3, Fe2O3 0.5, Al2O3 1.0, As2O5 1.0, SiO2 20.1, H2O [15.1], sum = 100.0%. This yields (Ca0.76Mg0.19)Σ0.95(Mn5.973+Fe0.053+)Σ6.02(Si2.80Al0.16As0.075+)Σ6.02(Si2.80Al0.16AS5+0.07)Σ3.03O16·7.01H2O, corresponding to the idealized formula. The strongest lines in the X-ray powder diffraction pattern are (d, I): 11.3, 100; 3.548, 30; 2.898, 30; 2.567, 40; 2.262, 25; 2.238, 25; 1.470, 25. Bostwickite is dark red in colour; hardness c. 1 (Mohs'); density (meas.)= 2.93 g/cm3. It occurs in radial aggregates of acicular compound crystals. Optically, bostwickite is biaxial negative with 2Vα = 25deg; α = 1.775, Β = 1.798, γ = 1.800;, dispersion strong, r > v; strongly pleochroic with α = β redbrown, γ = yellow-brown; absorption is α = β = γ. Bostwickite is named in honour of Richard C. Bostwick, collector and compiler of data on the minerals of Franklin and Sterling Hill.

A new species of Polygordiidae, Polygordius jouinae sp. nov., along with its distribution, habitat, and reproduction is described. Polygordius jouinae sp. nov., the first North American Polygordius, is a dominant member of macrofaunal communities on the inner continental shelf, and in bays and harbours from Massachusetts to southern New Jersey. It is distinguished from most other Polygordius species by its non-inflated, heavily ciliated pygidium, absence of pygidial glands, and a conical (rather than rounded) prostomium. The 18S SSU rDNA from P. jouinae sp. nov. was sequenced and represents the first named Polygordius species with a DNA reference in GenBank. Spearman rank correlation of sediment grain size with density of P. jouinae sp. nov. at a New Jersey site showed that density was significantly (P<0.05; N=92) positively correlated with the proportion of medium to very coarse sand and negatively correlated with the fine sand fractions. Ecologically, P. jouinae sp. nov. is an important macrofaunal species given its widespread distribution and its fidelity for coarse sand habitats. Thus, its relative abundance may be useful as an indicator of changing sedimentary conditions.

An isolated ichthyosaur coracoid from the Hornerstown Formation of New Jersey extends the geological range of the Ichthyosauria at least to the late Maastrichtian. The specimen cannot be referred to any known taxon but is too incomplete to be described as the type of a new species.

A new species of anatomically preserved Cupressaceae is described from the Upper Cretaceous Raritan Formation (New Jersey, USA). The fossils are charcolified isolated ovuliferous complexes that were studied by means of a combination of SEM images and micro-computed tomography (micro-CT), allowing the observation of morphological and anatomical characters. Each ovuliferous complex bears 3–4 anatropous winged seeds, disposed in one row on a thin medial part of the adaxial side of the ovuliferous complex. Based on the combination of characters such as ovuliferous complex morphology, arrangement of vascular tissues and resin canals, seed number and their morphology, orientation and disposition, these fossils are placed within a new species of the fossil genus Athrotaxites. The developmental stage of the specimens is analyzed base on comparisons with living representatives of the subfamily Athrotaxoideae (i.e., Athrotaxis spp.), which supports a post-pollination stage for these fossils. In addition, the new species is compared with other extant and extinct representatives of basal cupressaceous subfamilies. This new record from the Upper Cretaceous sediments of New Jersey further supports a wider distribution of the subfamily Athrotaxoideae during the middle part of the Mesozoic, as it has been also noted for other basal representatives of the family Cupressaceae.

A new species, Rariglanda jerseyensis, is described from well-preserved fusainized fossil flowers collected from the Late Cretaceous of New Jersey. Phylogenetic analyses and comparisons with extant and extinct taxa place R. jerseyensis within the monophyletic Ericales, sister to Clethraceae. The most distinctive feature of R. jerseyensis is a dense covering of conspicuous multicellular trichomes on the abaxial surface of the calyx. These multicellular trichomes appear to be glandular, and similar trichomes are found in several other, unrelated, Late Cretaceous fossils. In particular, the ericalean fossil Glandulocalyx upatoiensis bears the most similarity to R. jerseyensis, although differences in androecium and trichome characters clearly separate the two taxa. In addition, phylogenetic analyses confirm the position of G. upatoiensis within the Ericales, but place it within the sarracenioid clade, in a polytomy with Actinidiaceae and Roridulaceae. Past ecological studies associating trichomes with defense against herbivores and pathogens, coupled with the prevalence of multicellular trichomes on flowers among different lineages of fossils in the Cretaceous, suggest that glandular trichomes could have been an important adaptation against herbivore feeding during the Cretaceous.
