(Atheris squamigera) variable bush viper Venom not well studied, but likely hemotoxic. Bites rare, but at least one human fatality reported. No specific antivenom currently produced, but good paraspecific neutralization has been reported.
i wish that more people would take a page out of miyazaki’s book and actually learn how to deliver a pro-environmental message without coming across as annoyingly preachy or anti-technology and progress
Pentagonite with Cavansite on Stilbite - Wagholi Quarries, Wagholi, Pune District, Maharashtra, India
Pentagonite is the rare (very much so) dimorph of Cavansite. This means
that they are the same chemistry but are actually different crystal
forms, and thus different species. As rare as pentagonite is (the first
Indian specimens were only found many years after the first cavansites),
it is even more incredibly rare to find the two species in close
association as on this piece.
Locality: near Searchlight, Clark County, Nevada, USA
Amazingly, the mineral turquoise has totally pseudomorphed an animal bone, turning it a light green color. On rare occasions animals and humans die in the vicinity of ore bodies, primarily copper, and their skeletons are replaced cell by cell by the minerals. A bone replacement is essentially a pseudomorph similar to Turquoise after Apatite, and this is a very educational example of how we ourselves are “mineralized.” From the well-known pseudomorph collection of Ken Roberts. Specimens of this quality are very rare.
Unusual Tourmaline crystal -
Teófilo Otoni, Mucuri valley, Minas Gerais, Brazil
The crystal of very dark blue-black Tourmaline measures to 8.4cm striated, with a multi faced termination, but the intriguing parts are the four holes through the tourmaline. These could have been created by the tourmaline’s growth around a pre-existing mineral, possibly feldspar, that has since been naturally dissolved away, leaving the novel crystal formation. An unusual find in the world of tourmaline.
