Pencil Urchins Crucial to Hawaiian Literacy??

A new blog by Seattle based writer David B. Williams, "Stories in Stone-the Interfingering between people and rock" relates an interesting story of how the tropical Indo-Pacific echinometrid urchin Heterocentrotus mammilatus (aka the Slate Pencil Urchin) played an important role in the literacy of Hawaiians! Here's a quote from it:

The introduction of school slates and the use of sea urchin spines, along with other printed forms ultimately led to Hawaii having wide-spread literacy during the 19th century. Unfortunately, an overthrow of the Hawaii monarchy led to the banning of Hawaiian language in schools. The ban wasn’t lifted until 1986.

Neat! Go check it out!!

Thanks to David Williams for bringing this blog to my attention!

Starfish & Stamps of the Spiny Skinned!! aka What have you done for me philately?

Greetings!
Sorry to be so late with the new blog this week.. Monday for us in the US is a holiday (Martin Luther King's Day) and well..on Tuesday (January 20th) there was this minor bit of political bureacracy that we have to put up with every four years....Plus, I've been working on a few things.. that I will announce soon.. I hope to get back to "normal" next week...

So, today I thought I would just treat everyone to some really cool images I found of various countries that have made really UNCOMMON starfish species into POSTAGE stamps!!

How cool is that??? A nice gallery of these starfish stamps is found here at the WoRMS image gallery.

1. Odontaster validus-A frequently encountered Antarctic species on stamps from the Ross Dependancy (part of New Zealand)
2. Some unusual oreasterids from Papua New Guinea (Choriaster granulatus)


and one from New Caledonia (Halityle regularis)
3. A nice assemblage of tropical echinoderm stamps are published by the Sultanate of Brunei (thanks to Joyce for clarification)!
A nice little write up on these stamps is here.

4. And a cool assortment of cold-water invertebrates, including TWO asteroid species from the British Isles..Asterias rubens and Crossaster papposus
A more detailed treatment of these stamps can be found here.

5. Also Sea Urchins....

6. Sea Cucumber Stamps!

7. and even Crinoids & Ophiuroids!!

Another post on Friday and then I'll be BACK in full next week!

Archaeological Echinoderm Pt. 2! Sea Eggs and St. Boniface's Pennies!

(Ovum anguinum by Pliny)

So..whilst writing up the account earlier this week (go here to see pt. 1 about urchins in folklore), I hit a treasure trove of information on the role of fossil echinoderms in historical folklore! Here's a few more interesting bits about echinoid fossils from Northern Europe!

1. Sea or Snake Eggs. Many sea urchin fossils (these look somewhat like cidaroid urchin tests) were believed to have magical healing powers or other supernatural properties.

and one such story originates in Pliny's book Natural History as described in Oakley (1965):

According to an ancient Celtic tradition innumerable snakes twining together at mid-summer make a ball out of froth which they exude. It was called the ovum anguinum. If it could be stolen from the snakes it was an object of great magical power. It was said to be covered with a crust having excrescences like the suckers of a cuttle-fish. It possession ensured success in battle and disputes.

Further info on the whole snake angle can be found on this French website and the British Museum has a solid summary here.
From the accounts I could find these "sea eggs" aka "chalk eggs" or "snake eggs" could be used for a vareity of remedies including

1. "subduing acrid humours of the stomach"
2. sea-sickness remedies SO effective that some seamen would not travel WITHOUT having a "chalk egg" handy.
3. antiodes for poison

Apparently, the role of fossil sea urchins was not limited to Western cultures..Mortensen in his monograph also records this account:

It is of the greatest interest in this connection that some similar religious superstition with regard to fossil sea-urchins appears to exist in recnet days in India. Dr. Eigil Nielsen informs me that at a party in New Delhi a lady told him that in some places in India people place fossil sea-urchins on house-altars, adorn them with flowers, which must be put on fresh every day-otherwise some misfortune will happen. I have till now not succeeded in getting exact information about this matter.

2. The oh-so delicately named "Jewstone"
One kind of fossil sea urchin, Balanocidaris (from Jurassic and Cretaceous limestones) has very peculiar shaped spines. These were so-named because they were "commonly" obtained from Judea. (altho they were also called "petrified olives")

(images from the BMNH echinodea database).

Their shape was strongly suggestive that they would serve as treatment for bladder-related medical problems in accordance with "established magic principles"!!

3. Crinoids columnals aka St. Boniface's Pennies!
And of course, what kind of fossil record would we have without crinoid columnals? These were commonly used in the Bronze Age as beads.

In Germany, these were known as Bonifacius Pfennige or St. Boniface's pennies and were used as "fairy money" (whatever that happens to be). And in the North of England, they have been known since the 17th Century as St. Cuthbert's beads as indicated in this passage from Scott's Marmion (as recounted by Oakley, 1965).

But fain Saint Hilda's nuns would learn
If, on a rock by Lindisfarne,
Saint Cuthbert sits, and toils to frame
The sea-born beads that bear his name:
Such tales had Whitby's fishers told,

Archaeological Echinoderm! Fairy Loaves & Thunderstones!

Today's Echinoblog is inspired by the picture above. The original caption from Vol. 5 (1) of the Mortensen Monographs reads:

Skeleton of woman and child, surrounded by a wreath of sea-urchins, apparently Micrasters, found in a tumulus at Dunstable Downs, N. of London. From Worthington G. Smith. Man, the Primeval Savage, 1894.

So yes, what you are seeing is a ceremonial grave arrangement surrounded by fossil sea urchins!

Fossil sea urchins have played important roles in the early history of humans in various cultures...Today, let's look at a few of the better known ones..... (btw.. pt. 2 of this topic is here)

The sea urchin in question is Micraster, a fossil "irregular" sea urchin which occurs from the Upper Cretaceous to the Early Tertiary in Northern Europe and Africa.

(image from the BMNH Echinoidea database)

Fossil sea urchins and other echinoderms occur widely throughout Northern Europe and were apparently used quite frequently in several Mesolithic to Early Bronze Age human communities.

Fossil irregular sea urchins had several common names (for several different fossil taxa) and found their way into several ceremonial uses. Two are pretty well documented from Northern Europe.

1. "Thunderstones." Based on one account, it was believed that the "thunderstones" (i.e., Micraster and others...) had arrived in a thunderstorm and that it served as protection because 'where it had once struck it was not worth coming again'.

Extended notions of thunderstones believed that these followed ONLY after a "crashing thunderclap" and that the stone's landing created the noise!!

(Echinoblog Theoretical Reconstruction of "Thunderstone" hitting the Earth)

Others thought that thunderstones 'sweated' when it was certain that a storm was arriving.

Thunderstones were also made into axes and kept on pantry shelves because they "kept milk fresh and caused plenty of cream".

2. "Fairy Loaves". Differently shaped urchins had different names..

For example, some such as the oblong irregular urchin Echinocorys were called "Fairy Loaves"

probably due to their resemblance to loaves of bread..
A neat account of the role of these urchins as "Fairy Loaves" is presented by the BMNH. An excerpt from their essay on the subject:

The resemblance between these echinoids and round loaves inspired people in north-east Suffolk to place them as charms by the hearth in the hope that the baking bread would be influenced by the fossil's loaf-like shape. It is said that families who kept fairy loaves in their houses could ensure they would always have bread.

Failure of the weekly bread to be properly formed was attributed to witchcraft against which Fairy Loaves had protective powers. The powers given to these fossils underlines just how vital bread and breadmaking were to daily life and village economy in Suffolk during times gone past.

The fairy loaf in Suffolk was also called pharisee-loaf which at some point became facy-loaf. Farcy is a disease in horses and it has been suggested that the fossils were also used as charms by farm horsemen .

A look at one of the world's rarest starfish!

As many of you may have realized, I was away for about two weeks on holiday travel...see San Francisco, hang out with my colleagues at the California Academy of Sciences..have some dim sum..(*mmmm..dim sum*), so FINALLY...all good things must end and I return to DC to find THIS splendid specimen awaiting me...
Several months ago I had arranged for a loan from the TePapa Museum in New Zealand to examine a specimen of a rare species of deep-sea starfish that had been discovered from the SubAntarctic. (Thanks to my colleagues at the USARP for arranging to bring the specimen back to the US!)

The specimen is a member of the MYXASTERIDAE, a group of truly deep-sea (1000-3000 m) starfishes, which is one of, if not, the rarest group of starfishes in the world. Nine species in three genera are found in the Atlantic, Indian and the Pacific Oceans.
What makes any animal rare?? A combination of abundance as well as frequency of occurrence.

When most people think of the rarest deep sea echinoderm/star shaped thing, many automatically think of the so-called "sea daisy" Xyloplax which I have covered here and here.

What makes myxasterid starfish MORE rare then Xyloplax? While its true that Xyloplax has only been encountered once or twice every 15 years..there are actually about 100 specimens of each species known.

How many myxasterids are known?

Here is a shot of approximately HALF of the total number of SPECIMENS in the world. About ONE or TWO specimens of each species is known. That means you can count the TOTAL number of actual individual specimens on your hands and toes. You can count the number of specimens of each species in each genus on ONE HAND. (and just to brag-I have seen almost all of them)

But of course, there is ALWAYS more to the mystique of rare animals then their rarity.

What evolutionary novelty makes myxasterids so interesting??

Morphologically, they have an "intermediate" body form between two very evolutionary successful (and familiar) groups of starfishes:

the SOLASTERIDAE or sun stars:
and the PTERASTERIDAE or the Slime or Cushion Stars.

So, you have a starfish with multiple long-arms IN ADDITION to structures that ostensibly enable it to project the huge amounts of mucus that pterasterid starfish produce?

In fact, the type name "Myxaster" comes from the Greek Myxa for slime and of course, "aster" for star. (note that this name is similar to the hagfish name Myxine...)

Plus, you have a really SOFT slimy body, covered by fine hyaline spines on a creature that is seldom if ever encountered and you have yourself ....a mystery....

Do I have a new species?

What do they eat?

Are they related to the starfish species everyone thinks?

Are they ACTUALLY really rare??

A great way to kick off the New Year! Happy 2009!!
