The Pediacus Shuckard fauna of Asia and Australasia is revised. Eighteen species are recorded, described and illustrated from the regions and a key to species is provided. Nine new species are described: Pediacus australis sp. nov. (Australia, Papua New Guinea, Philippines, Thailand), P. carinatus sp. nov. (Indonesia, Malaysia, Thailand), P. fujianensis sp. nov. (China), P. japonicoides sp. nov...

We revise the four species of Kaszabister Mazur, 1972, one of which, Kaszabister barrigaisp. n., is described as new. The other species in the genus are Kaszabister rubellus (Erichson, 1834), Kaszabister ferrugineus (Kirsch, 1873) and Kaszabister carinatus (Lewis, 1888). The species are principally known from the subtropics of South America, with one in Central America. Lectotypes are designate...

Articulated embryos from the Lower Jurassic Elliot Formation of South Africa are referable to the prosauropod Massospondylus carinatus and, together with other material, provide substantial insights into the ontogenetic development in this early dinosaur. The large forelimbs and head and the horizontally held neck indicate that the hatchlings were obligate quadrupeds. In contrast, adult Massosp...

Signaling individuals must effectively capture and hold the attention of intended conspecific receivers while limiting eavesdropping by potential predators. A possible mechanism for achieving this balance is for individuals to modulate the physical properties of their signals or to alter the proportion of time spent signaling, depending upon local levels of predation pressure. We test the hypot...

was bitten, while collecting grass, 011 the dorsum of the left hand near the root of the middle finger. He ran to the hospital within 15 minutes after the bite. No ligature was put on.

A systematic account of crinoids from the Upper Coniacian-Lower Campanian of the southwestern margin of the Holy Cross Mountains in southern Poland is presented. Seven crinoid taxa [Marsupites testudinarius (von Schlotheim), Bourgueticrinus ellipticus (Miller), Bourgueticrinus sp., I.? granosus Valette, Isocrinus? sp., Nielsenicrinus carinatus Roemer and Austinocrinus bicoronatus (von Hagenow)]...
