Flea market finds including seashells, fossils, mineral specimens. My fave is the hag stone and the fossilized shells.

Juvenile bivalve mollusc, Lima sp. (10x). Dr. Greg Rouse, Scripps Institution of Oceanography.

Bivalvia is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. Bivalves have no head, and they also lack a radula. They include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders.

We have reached the point where I’m reblogging this to my conversion blog for people who might need the resource

Anyways, behold: stuff we know. because. radioactivity. isotopes. And other stuff that I don’t feel like explaining.

Also these meme should be resurrected anyway o-o

I’m partial to the Devonian, myself.

PETRIFIED WOOD from the Chinle Formation of Arizona. Colors are dependent on the chemistry of the percolating waters. Approximate age is 225 million years old (Triassic).

My #wcw is the anomalocaris, super predator of the Cambrian period. This bitch existed roughly 43 million years and is responsible for the little w shaped bite marks found on trilobites and other fossils.

INOCERAMUS “Strong pot” Early Jurassic-Late Cretaceous, 189-66 million years ago

This genus of extinct bivalve clam flourished throughout the age of the dinosaurs. Calcite deposits would’ve given its shell a pearly appearance, and considering it could grow to over five feet in diameter, that’s a lot of shell!

It is argued that some species of Inoceramus actually belong to other genera, like Platyceramus, Sphenoceramus, or Volviceramus, but few experts care, as clams were the least interesting things alive at the time.

2018: Glass House Mountains, Queensland. Lovely example of volcanism endemic in eastern Australia during the Tertiary.

LGBT Zoology Pride!

As June is pride month I thought I’d post some animals that colourations match LGBT pride flags to celebrate evolution’s rainbow in my own nerdy science way.

Previous flags here: Lesbian | Gay |

Mwanza flat-headed Rock Agama (Agama mwanzae)

Endemic throughout Tanzania, Rwanda, and Kenya, the male’s bright colouration of pink, red and blue mean that these lizards are also commonly called the spider-man agama.

Thunderbolt Crayfish (Cherax pulcher)

The thunderbolt crayfish is a proprietary variant bred from two different species from the Cherax genus resulting in the bright blue, pink and purple colouration, which make them popular pets. Species in the Cherax genera are found typically in Australia and New Guinea.

Lilac-breasted roller (Coracias caudatus)

Found throughout sub-Saharan Africa and the southern Arabian Peninsula, these birds are considered the (unofficial) national bird of Kenya.

Flower Beetles (Smaragdesthes africana oertzeni)

Smaragdesthes africana are a common beetle species found throughout the afrotropical region, more commonly known as flower beetles due to the range of various shades of iridescence throughout subspecies. The subspecies oertzeni is a strikingly purple, blue and pink colour.

Superb Leafwing (Fountainea nessus)

These striking butterflies occur in the eastern Andes (from Colombia to Bolivia) with the males forewings baring these bright pink-purple bands overlaid with a bright blue sheen. The underside of their wings are patterned brown in order for them to cryptically resemble their surrounding environment such as tree trunks and leaf litter.
