“…Apart from this material, Eusthenodon remains were previously recorded from the Famennian of central Russia (Andreyevka-2 locality in the Tula Region; Alekseev et al 1994), Australia (Eden, New South Wales; Ahlberg et al in press, and Grenfell, New South Wales;Young 1993), and South Africa (Witpoort Formation; Gess and Hiller 1995;Anderson et al 1999). However, none of the Russian, Australian and South African specimens has yet been described in detail.…”

ABSTRACT. Remains of two large sarcopterygians are described from Famennian deposits in Belgium. One of them is referred to Eusthenodon wa Èngsjo Èi Jarvik; it is the ®rst occurrence of this genus in Belgium. The other, much larger one, appears to be a tristichopterid. It has a postspiracular; size and shape of the mandible similar to those of Platycephalichthys skuenicus and P. bischof®; snout and cheek patterns close to those of Eusthenodon; unusual shape of the supratemporal resembling that of Hyneria, Mandageria and Platycephalichthys skuenicus; and tooth histology quite similar to that of Eusthenodon and Platycephalichthys.

“…2004; Clack 2006). Similarly, changeover from a Devonian antiarch placoderm‐porolepiform sarcopterygian biota to a Carboniferous chondrichthyan‐actinopterygian assemblage in Russia was dismissed as a local phenomenon (Alekseev et al. 1994; Clack 2006).…”

: Fishes include more than half of all living animals with backbones, but large‐scale palaeobiological patterns in this assemblage have not received the same attention as those for terrestrial vertebrates. Previous surveys of the fish record have generally been anecdotal, or limited either in their stratigraphic or in their taxonomic scope. Here, we provide a broad overview of the Phanerozoic history of fish diversity, placing a special emphasis on intervals of turnover, evolutionary radiation, and extinction. In particular, we provide in‐depth reviews of changes during, and ecological and evolutionary recovery after, the end‐Devonian (Hangenberg) and Cretaceous–Palaeogene (K–Pg) extinctions.

“…The former environment would very likely have been subject to tidal influences; the latter is less certain but by no means impossible. The case for a tidally influenced environment also applies to the tetrapods Elginopteron [16] (non-marine fluvial deposits, Scotland) and Tulerpeton [17] (coastal lagoon, Russia). By contrast, Ichthyostega [18] and Acanthostega [19], the earliest known tetrapods with fairly complete body fossils (later than Elginopteron, for which only fragmentary remains are known) are associated with a non-marine inland basin (Greenland), a more ambiguous tidal zone.…”

Dynamical, biological and anthropic consequences of equal lunar and solar angular radii

The nearly equal lunar and solar angular sizes as subtended at the Earth is generally regarded as a coincidence. This is, however, an incidental consequence of the tidal forces from these bodies being comparable. Comparable magnitudes implies strong temporal modulation, as the forcing frequencies are nearly but not precisely equal. We suggest that on the basis of palaeogeographic reconstructions, in the Devonian period, when the first tetrapods appeared on land, a large tidal range would accompany these modulated tides. This would have been conducive to the formation of a network of isolated tidal pools, lending support to A. S. Romer's classic idea that the evaporation of shallow pools was an evolutionary impetus for the development of chiridian limbs in aquatic tetrapodomorphs. Romer saw this as the reason for the existence of limbs, but strong selection pressure for terrestrial navigation would have been present even if the limbs were aquatic in origin. Since even a modest difference in the Moon's angular size relative to the Sun's would lead to a qualitatively different tidal modulation, the fact that we live on a planet with a Sun and Moon of close apparent size is not entirely coincidental: it may have an anthropic basis.
