Rare productid brachiopods,
ichnofossils, petroleum, and iron staining do not detract from the stone's architectural qualities.
The
ichnofossil bed lies near the top of 10 m of interbedded siltstone and sandstone (Kennedy and Gibling 2011; Kennedy et al.
(2004):
Ichnofossils from the type area of the Grund Formation (Miocene, Lower Badenian) in northern lower Austria (Molasse Basin).
Palaeophycus is restricted to the Cruziana, is the genus attributed to this
ichnofossil. It also appears in the Palermo Formation (Fernandes et al., 2002; Netto, 2000; Netto et al., 2012), partially chrono-correlated to the Tatui Formation.
The first dung beetle retrieved from coprinisphaeridae

The left side of the cephalon bears an about 1 mm long cavity, representing a tiny
ichnofossil of the genus Arachnostega (see Fatka et al.
In his final paper on tetrapod
ichnofossils, Matthew (1910) described three new ichnospecies, Hylopus (?) variabilis, Nanopus (?) vetustus and Bipezia bilobata, from the Upper Carboniferous Lancaster Formation at 'Fern Ledges', Saint John, New Brunswick (Fig.
<<Cambrian>>
ichnofossils in the Armorican Quartzite of Central Portugal.
The reason for this is that the Coastal Group has the advantages of excellent coastal exposures and diverse
ichnofossils without the disadvantages, particularly in the White Limestone Group, of karstification and case hardening.
The common
ichnofossil Chaetosalpinx sibiriensis Sokolov, 1948 (Table 1, Fig.
In fact, a correlation of the Pena Segra locality (Cantabrian mountains) with the "zone 4" of the Rajejac Formation has been already proposed (Gand et al., 1997) based on
ichnofossil biozones.
