The present study describes the design and structure of the masseter muscle of the blind mole rat (Spalax leucodon). The blind mole rat, which emer- ged 5.3–3.4 million years ago during the Late Pliocene period, is a subterranean, hypoxia-tolerant and cancer-resistant rodent. Yet, despite these impressive cha- racteristics, no information exists on their masticatory musculature. Materials and methods: Fifteen adult blind mole rats were used in this study. Dissections were performed to investigate the anatomical characteristics of the masseter muscle. Results: The muscle was comprised of three different parts: the superficial mas- seter, the deep masseter and the zygomaticomandibularis muscle. The superficial masseter originated from the facial fossa at the ventral side of the infraorbital foramen. The deep masseter was separated into anterior and posterior parts. The anterior part of the zygomaticomandibularis muscle arose from the snout and passed through the infraorbital foramen to connect on the mandible. -

Oreodonts of the Tick Canyon Formation , Southern California
PALE0B10s Contributions from the University of California Museum of Paleontology, Berkeley No. I June 15, 1967 OREODONTS OF THE TICK CANYON FORMATION , SOUTHERN CALIFORNIA by David P. Whistler OREODONTS OF THE TICK CANYON FORMATION, SOUTHERN CALIFORNIA BY DAVID P. WHISTLER In 1940, Richard H. Jahns reviewed the stratigraphy of the nonmarine Mint Canyon Formation in the eastern part of the Ventura Basin and separated from it a new formation and fauna. Previous to this work, a controversy existed as to the age of the Mint Canyon Formation, for it contained vertebrates considered indicative of both the Miocene and Pliocene (Kew, 1924, Maxson, 1930, and Stirton, 1933). As a partial solut,ion to this controversy, Jahns demonstrated the presence of an erosional unconformity low in the nonmarine sequence which indicated a shift in source area. He redefined the beds below the unconformity as the Tick Canyon Formation (Jahns, 1940, pp. 163-66). Additional fossils discovered in the Tick Canyon Formation since Maxson's work, and certain of the forms described by Maxson, comprise the Tick Canyon fauna. Only two specimens described by Maxson are from the Tick Canyon Formation, UCMP 30046, the type of Miolabis californicus and UCMP 23852, a dentary fragment of a Parahippus. Neither of these permitted a definitive age determination. The additional fauna described by Jahns indicates an Arikareean mammalian age (early Miocene), and there is a noteworthy temporal hiatus between the Tick Canyon fauna and the over lying Mint Canyon fauna. In addition, faunas comprising three mammalian ages, late Barstovian, and earlier and late Clarendonian, are now recognized from the Mint Canyon Formation, but this is not the principal concern of this paper. -

No seed or foliage species is shared between the Northern and Southern Hemisphere fossil sites and Hydrochory only a few species are shared between the Jurassic and Cretaceous assemblages in the respective regions. Free- Angiosperms sporing plants, including a broad range of bryophytes, are major components of the studied assemblages and Conifers attest to similar moist growth habitats adjacent to all four preservational sites. Both simple unadorned seeds and winged seeds constitute significant proportions of the disseminule diversity in each assemblage. Anemochory, evidenced by the development of seed wings or a pappus, remained a key seed dispersal strategy through the studied interval. Despite the rise of feathered birds and fur-covered mammals, evidence for epizoochory is minimal in the studied assemblages. Those Early Cretaceous seeds or detached reproductive structures bearing spines were probably adapted for anchoring to aquatic debris or to soft lacustrine substrates. -

Shell Microstructures in Early Cambrian Molluscs
Shell microstructures in Early Cambrian molluscs ARTEM KOUCHINSKY Kouchinsky, A. 2000. Shell microstructures in Early Cambrian molluscs. - Acta Palaeontologica Polonica 45,2, 119-150. The affinities of a considerable part of the earliest skeletal fossils are problematical, but investigation of their microstructures may be useful for understanding biomineralization mechanisms in early metazoans and helpful for their taxonomy. The skeletons of Early Cambrian mollusc-like organisms increased by marginal secretion of new growth lamel- lae or sclerites, the recognized basal elements of which were fibers of apparently aragon- ite. The juvenile part of some composite shells consisted of needle-like sclerites; the adult part was built of hollow leaf-like sclerites. A layer of mineralized prism-like units (low aragonitic prisms or flattened spherulites) surrounded by an organic matrix possibly existed in most of the shells with continuous walls. The distribution of initial points of the prism-like units on a periostracurn-like sheet and their growth rate were mostly regular. The units may be replicated on the surface of internal molds as shallow concave poly- gons, which may contain a more or less well-expressed tubercle in their center. Tubercles are often not enclosed in concave polygons and may co-occur with other types of tex- tures. Convex polygons seem to have resulted from decalcification of prism-like units. They do not co-occur with tubercles. The latter are interpreted as casts of pore channels in the wall possibly playing a role in biomineralization or pits serving as attachment sites of groups of mantle cells. Casts of fibers and/or lamellar units may overlap a polygonal tex- ture or occur without it. -

The image on the cover and title page is a stylized dendrogram of paraphyly (see Plate 1.1). This is, in macroevolutionary terms, an ancestral taxon of two (or more) species or of molecular strains of one taxon giving rise to a descendant taxon (unconnected comma) from one ancestral branch. The image on the back cover is a stylized dendrogram of two, genus-level speciational bursts or dis- silience. Here, the dissilient genus is the basic evolutionary unit (see Plate 13.1). This evolutionary model is evident in analysis of the moss Didymodon (Chapter 8) through superoptimization. A super- generative core species with a set of radiative, specialized descendant species in the stylized tree com- promises one genus. In this exemplary image; another genus of similar complexity is generated by the core supergenerative species of the first.
