David Unwin, however, indicated in 2001 that it was a species of Coloborhynchus, then he called it as C. moroccensis and being a member of the Ornithocheiridae. This has been controversial. In the same year, Michael Festnacht suggested it was more similar to Anhanguera due to the wide end of the snout. In 2009, Kellner considered that Siroccopteryx, Coloborhynchus clavirostris and Uktenadactylus probably formed together a clade within Anhangueridae.

Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes.

However, only two different pterosaur taxons have been described. Mader \u0026amp; Kellner (1999) (Full reference: B. J. Mader and A. W. A. Kellner. 1999. A new anhanguerid pterosaur from the Cretaceous of Morocco. Boletim do Museu Nacional - Geologia 45:1-11) described the Coloborhynchus moroccensis species, belonging to the Anhangueridae family, which lived at the middle of the Cretaceous (between the Albian and Cenomanian stages, about 105 million years ago). Remains have been discovered in Morocco. Another alternative combination in the nomenclature of this taxon is Siroccopteryx moroccensis.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000000\" style=\"color: #000000;\"\u003e\u003cspan face=\"Arial\" style=\"font-family: Arial;\"\u003e\u003cspan size=\"2\" style=\"font-size: small;\"\u003ePhylogeny: The descriptors of Siroccopteryx placed this genus in the family Anhangueridae, sensu Kellner. David Unwin, however, indicated in 2001 that it was a species of Coloborhynchus, then he called it as C. moroccensis and being a member of the Ornithocheiridae. This has been controversial. In the same year, Michael Festnacht suggested it was more similar to Anhanguera due to the wide end of the snout. In 2009, Kellner considered that Siroccopteryx, Coloborhynchus clavirostris and Uktenadactylus probably formed together a clade within Anhangueridae.

The lithology of this body of sediment is characterized by the dominance of sandstones (also known as arenites) and fluvial gravel, of siliceous nature. Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes. The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge.

Because of this, any possibility of finding articulated rests is very rare, since the rests of dead animals where transported and deteriorated. That is why only the most robust bones or the most stable parts are usually preserved.
