Notosilesitoides

Coming soon

This ammonite features a whorl that resembles a coiling snake, an evolved whorl with ribs that branch into two, a polygyral (many whorls), and a very small shell. Three specimens of this species have been collected; one has been named the holotype; if living, they feature a soft body with eight long tentacles and nautiloid eyes.

Ammonites use their ink to help their prey get away. When they feel threatened, they can shoot large amounts of ink into the water using their siphon. Scientists believe that by pumping air through the inside chambers of the shell, the air-pump-like siphuncle helped create buoyancy and transport ammonites through the water. Ammonites and nautiluses, on the other hand, have thick exterior shells that protect them from predators.

Because of this species, there was abundant life with possibly marine reptiles or dinosaurs dominating in Catanduanes state. In the Yop Formation at San Andres, Catanduanes found corals, protozoa, belemnites, and possibly marine dinosaurs. Considered the second precursor of animal life in the Philippines, after Perisphinctes, mammals, birds, and crocodiles altogether.

Nine Aptian to early Albian ammonoid species, apparently from the Yop Formation in Catanduanes Island, Philippines, are described herein: Goretophylloceras, Eogaudryceras (or Eotetragonites), Notosilesitoides philippinensis, Miyakoceras tanohatense, Neosilesites nepos, Neoastieria, Marshallites miyakoensis, Colombiceras satowi, and Colombiceras. This is the first systematic palaeontological report of Cretaceous ammonoids from the Philippines. Among the described species, Notosilesitoides philippinensis is proposed as a new genus and species.

Nautiluses and ammonites are shy toward humans and unique among other cephalopods, though, because they have hard outer shells that help protect them from predators.

This fauna shows close similarity to that of the Tomochi Formation, Choshi Group, and Miyako Group in Japan. These faunas were in a warm current regime that extended from the equator. The age and palaeogeographical significance of the assemblage are discussed.

The ammonite isn’t tame because it is stupid.
