Would make for an awkward family reunion

Acanthodes bronni. The species name has "bro" in it, and according to a study undertaken by Davis, Finarelli and Coates, the shark-like A. bronni is a member of the family.

Wikipedia: Acanthodes bronni; your relative, a "few times" removed.
For an understanding of the position human beings find themselves in comparison to A. bronni, have a read of this blogger post: Common ancestor for humans and sharks: Acanthodes bronni. This post provides a brief history of the lineage and traits of Gnathostomes (everything with a spine and jaws).

Love your Brother shark.

Evolution; a fact

It was pointed out to me by a rather ingenious mind that:


"Evolution is a fact".



She followed this statement with:


"It sounds even better translated to Polish:
Ewolucja jest faktem."




The Polish are wise people.

Nonsensical pseudo-science

The Creation Museum... where dinosaurs
become "Missionary Lizard(s)"

"Chicken" nuggets would have been bigger. . .

What saved the Dinosaurs?

Well... if you put some thought into it... one could argue that the need for a tangible, genuine monster/behemoth from Biblical literature for those who need proof, the determined progress of palaeontologists, the excitement in the enormity of something so unbelievably awesome and the adulation of children from all walks of life... oh yes, and the support of film makers (thank you Spielberg - no, seriously... thank you).

But evidently, they didn't survive in the living diversity as they once did before obliteration - just smaller, more advanced variations... and invariably more delicious (having only present-day poultry to go by this could only be speculation... for now).

Could be a cute dogfish??

How could you not love this face?!?


This ADORABLE little face belongs to the African lungfish. It is one of the more advanced species of lungfish, with the Queensland or Australian lungfish being the most primitive (QLD species has only a single "lung", has lobe-fins similar to the coelacanth, and is the only lungfish species which can breathe through its gills - others gulp air as the gills are no longer efficient - therefore it is the only lungfish that cannot live out of water but must instead remain moist [other species may live for several months out of water in burrows etc]).

Another interesting thing to note, this African lungfish looks like Rosie, a King Charles spaniel...

*note the resemblance*

Top 5 Fossil Discoveries (IMO)


-1- Materpiscis "Mother fish"
Ancient fish from Australia's Kimberley region, c.380 million years ago. Oldest known fossil displaying viviparous characteristics (live birthing) in the fossil record.

-2- Gogonasus
Ancient fish from the primitive tropical Australian reef 380 million years ago. Its breathing structure on its head, and forearm lobe-fin joints were precursors to the middle ear and limbs (radius and ulna). Gogonasus now replaces Quebec's Eusthenopteron (the original "missing link" in terms of early tetrapod development) in the tetrapod relationship. Since it's so ancient, this pushes the first appearance of these features further back in the fossil record.

-3- Darwinius masillae "Ida"
The most complete skeleton of the earliest stage of human - the key "missing link". Small, lemur-like fossil believed to be the earliest stage of human evolution. Not related to lemurs due to the lack of dew claw on the forelimbs and there is not a fused tooth comb (both characteristics are primary features of lemur).

-4- Homo floresiensis "Flores Man" aka: Hobbit
Potential to rewrite human history. Believed to be a separate species of homonid from humans, but appeared to exist around the same time as early H. sapiens (hobbits were founds on the Idon Flores while humans inhabited the rest of the world). Possible disease and/or rare genetic disorder caused their shorter stature.

-5- Megalosaurus bucklandii "Giant lizard"
The first dinosaur (besides birds) to be scientifically described and subsequently named. It came upon the unfortunate name "Scrotum humanum" by Richard Brookes in 1763 due to its identification by Reverend Plot as the femur of a giant human (as described in the Bible). Its appearance was believed to be a long limbed, quadrupedal dog-like crocodile before coming to its more correct form.
