Too tired right now to comment. But it was a good experience fund-raising for Palaeontology at the museum.
Fund-raising walk
Fossil – time period match game
game components photo source : Lorie Pierce
The disco party event at the museum last night was rocking, in more ways than one. Party-goers were invited to match 4 fossils with the time periods the original animal or plant lived within.
Since the focus for the evening was all things African, the fossils were specifically picked from the collection to represent Morocco, Egypt, Zimbabwe and Madagascar. Since the no actual bones of the dinosaur Spinosaurus were available, a plastic model and a reproduction claw were used as samples. Teams who were successful in making the match received stickers portraying dinosaurs, pterosaurs, icthyosaurs and ancient mammals. Since the participants were allowed to make as many guesses as they wanted, everyone who tried ended up a winner….while learning about ancient life in Africa at the same time.

Definitely a quiz we will repeat.
I'm atwitter
So many of my interests are aligning this week on Twitter.

Kenojuak Ashevak doodle
Google Doodle to commemorate Kenojuak’s 87th anniversary of birth
The Google Doodle has become a way to deciminate information about important events and people. Today the great Inuit artist Kenojuak Ashevak was honoured in a doodle that draws on the spirit of her paintings. She passed away almost two years ago, outliving 3 husbands and many children.
Her Enchanted Owl print from 1960 is a classic. The image has graced many calendars, note cards and a Canadian postage stamp.

Perhaps museums can find small ways, like Google uses the doodle, to highlight aspects of their collection. A doodle or a trivia fact could be posted on the museum website or sent out by Twitter or other social media.
Precious stones

The next mini-museum event off-site will feature Rocks, Gems and Space. Children will be making pendant necklaces, jeweled paper crowns, and volcanoes, as well as using cylinder seals to create writing in clay.
This beautiful Greek woman is being shown with her worldly possessions. Her maid and her jewelry box filled with gems, silver and gold. Originally a necklace dangled from the outstretched fingers of her right hand and there was a jeweled earring in her left ear. However, grave robbers removed those pieces in antiquity.

I have a particular fascination with sea life and follow several Twitter feeds that relate to all things maritime.Today this photo popped up @echinoblog

Common birds in steep decline
chart from stateofthebirds.org
It’s a headline you hate to read. Many of the wonderful birds of my youthful days in the backyard and neighbourhood fields, are now in steep decline according to a recent State of the Birds 2014 report.
To me it is unbelievable that these birds may go the way of the Passenger Pigeon that has been extinct now for 100 years.
Museums have a central role in the stewardship of nature’s wonders and my museum’s Centre of Discovery for Biodiversity focuses on birds as well as other species in peril.
sightings – Glanochthon
The problem with blogging about a specimen before a proper identification sign has been installed, is that you might get your identification wrong.
Case in point is the Glanochthon, recently installed in a prominent central location in the museum. Sources in the Palaeontology Department confirm the identity as:
Glanochthon sp., Permian, Germany, purchased Tucson 2013 (the label copy has been supplied by curatorial but not yet installed)
Additional information from Wikipedia shows:
“Glanochthon is an extinct genus of temnospondyl amphibian from the Early Permian of Germany. Fossils have been found from the Meisenheim Formation in the Saar–Nahe Basin.” Wikipedia
Tiktaalik features photo source : http://tiktaalik.uchicago.edu/meetTik2.html
My original thinking was that the tetrapod was a cast of the famous Devonian missing link animal, Tiktaalik.
Tiktaalik roseae, better known as the “fishapod,” is a 375 million year old fossil fish which was discovered in the Canadian Arctic in 2004. Its discovery sheds light on a pivotal point in the history of life on Earth: when the very first fish ventured out onto land.
Various fishapods artist : Dave Sousa
In Late Devonianvertebrate speciation, descendants of pelagiclobe-finned fish – like Eusthenopteron – exhibited a sequence of adaptations:
- Panderichthys, suited to muddy shallows;
- Tiktaalik with limb-like fins that could take it onto land;
- Early tetrapods in weed-filled swamps, such as:
- Acanthostega which had feet with eight digits,
- Ichthyostega with limbs.
Descendants also included pelagic lobe-finned fish such as coelacanth species. In 2000 P. Ahlberg et al. described a transitional form from fish to tetrapod, the Livoniana. This creature dates 374 – 391 million years ago, a successor to Panderichthys. wikipedia

sightings – My babies are growing up
Since it opened 11 months ago, I have visited the new aquarium on 22 occasions. The cuttlefish and octopuses have been a main draw for me. Yesterday was an exceptional day. Finally the summer crowds have dwindled and the school groups are not yet showing up at the door. It was a peaceful experience. One could get near the tanks and spend time composing photographs. Plus staff were out feeding some animals and cleaning tanks in full scuba gear.
The smaller octopus was moving around its tank and new sea nettles were on display.
However, my heart went out to the baby cuttlefish whom I’ve seen grow up from eggs the size of a large (black) pearl. Now they are big enough and mobile enough to track them on video.

The new Atlantic sea nettles are a study in gracefulness…unless they get tangled up in another jelly’s tentacles.

Unfortunately, I cannot show you the cuttlefish movies I took as the files are too large. Will work on how to resolve that issue as they are magical to see in motion.
#Remembering Martha
passenger pigeon exhibit photo source : Lorie Pierce
Exactly one hundred years ago today, the last known passenger pigeon died at the Cincinnati Zoo at the age of 29. Known as Martha, after the US first Lady Martha Washington,the passenger pigeon’s formal name is Ectopistes migratorius. The taxidermied specimen is now housed in the Smithsonian Museum.
The Royal Ontario Museum has opened an exhibit recognizing this sad anniversary, which is also expanded into a second case showing current birds who are in danger due to habitat loss and other threats.
