100 Years – 100 Objects: Specimens of the Dooley-Selden Expedition

The Houston Museum of Natural Science was founded in 1909 – meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.

This description is from Dan, the museum’s curator of vertebrate zoology. He’s chosen a selection of objects that represent the most fascinating animals in the Museum’s collections, that we’ll be sharing here – and at 100.hmns.org- throughout the year.

The Dooley-Selden team led the first HMNS mounted expedition. In 1959, HMNS’ first Curator, Tom Dooley, was invited by Board Member Selden to collect specimens in the northern (Saharan) region of what was then Tanganyika (today Tanzania). The objective of the expedition was to collect specimens for exhibition at the museum. Nearly 100 specimens were collected, including a vast array of birds and ungulates (hoofed mammals), as well as a few carnivores and small mammals.

A Lost Persian Army Returns

The place is the famous Siwa Oasis in Egypt. The time is 525 B.C.  Ancient Egypt is but a former shadow of itself. Tutankhamun has been dead and buried for 800 years (and his tomb plundered twice already by now). Slowly but surely, Egypt’s power was fading as it was drawn into the orbit of mightier empires in the region.

During the 6th century B.C., Egypt was plagued by massive internal unrest. Egyptian armies were involved in expeditions heading south into Nubia, as well as into southern Palestine. Greek-speaking mercenaries were now gainfully employed in Egypt. Greek merchants even received permission to settle in their own city, Naucratis, in the Nile delta. Things were definitely different in Egypt and they were about to take a turn for the worse in 525 B.C.

Cambyses II, ruler of the Persian Empire, invaded Egypt in that year. Psammetichus III faced the Persian army at the great frontier fortress of Pelusium eastern gateway into Egypt. The Egyptian forces and their Greek mercenaries were no match. The king fled to Memphis, where he was captured and taken to Susa, the Persian capital. One can only imagine what his fate was.

Greek historian Herodotus, father of history writing, lived a mere 75 years later and wrote about this momentous event. He relates how the Persian king sent off an army – of 50,000 soldiers no less – to destroy the oracle located in the Siwa Oasis. It is alleged that the oracle had predicted the king’s downfall, and Cambyses was having none of it. Yet the oracle proved to be right. The army never reached its destination and was swallowed up by the desert. Cambyses did eventually bite the dust as well in 522 B.C.

Then the sands of time and the desert covered up the story of the army that set off to destroy the oracle. Eventually, it was relegated to the realm of legend. Numerous expeditions were launched to find it, but without success.

Until….

Until relatively recent discoveries in the desert now seem to have located the unfortunate Persian army. Relatively recent indeed; it appears that for the last 13 years two Italian brothers, Angelo and Alfredo Castiglioni, undertook five expeditions in search of Cambyses’ troops. They claim they have found good evidence of Persian-era and Persian-style military gear in the Egyptian desert. The media are buzzing with the news. Numerous online videos have popped up on the subject, showing the Italian and Egyptian teams working at a rock shelter in the desert and finding Persian arrow heads, a partial sword or dagger and bits and pieces of horse gear.

Is this for real? Are we dealing with something else altogether? Time will tell. For now, it appears very likely that the lost army has been found. As they say, stay tuned. I am sure a documentary will soon appear on TV. I wonder if a book is coming out soon as well….

Leonids Meteor Shower Tonight!

Don’t miss out on your chance to see the Leonids meteor shower, tonight and early tomorrow morning. It won’t be as strong as the yearly December Geminids or August Perseid meteor showers. However, the Leonids meteor shower could produce as many as 500 meteorites in an hour during its peak, which will be in Tuesday’s early predawn hours.

The Leonids will be less frequent and appear weaker this year than at the turn of the century. This is because from 1999 to 2002, the Earth was moving through a clump of debris left by comet Tempel-Tuttle. In those years the Leonids were strong enough to be considered a storm (over 1,000 meteorites per hour).

Now Tempel-Tuttle has receded from the Sun, taking its main debris clumps with it.  Therefore, the Leonid showers aren’t as dramatic anymore, typically averaging only about one every few minutes.  The 2009 Leonids are expected to be stronger than usual, but not nearly as good as at the beginning of the decade.  Although they may be few in number, many Leonid meteors are quite bright.

The meteors will seem to radiate from the constellation Leo, which will be high in the east (hence the name of the shower).  You’ll see approximately one meteor every 2 or 3 minutes, or fewer if clouds or city lights are present.

100 Years – 100 Objects: Nodipecten fragosus

The Houston Museum of Natural Science was founded in 1909 – meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.

This description is from Tina, the museum’s associate curator of malacology. She has chosen a selection of objects that represent the most fascinating shells and animals in the Museum’s collections, that we’ll be sharing here – and at 100.hmns.org- throughout the year.

Lion’s Paws – Nodipecten fragosus (Conrad, 1849)

Nodipecten fragosus - Ventral View - largeThe Nodipecten fragosus is a member of the Pectinidae family, and ranges from Cape Hatterus, North Carolina through Florida, and the Gulf of Mexico. The colors are variable from brown, purple, pink, orange, red, to yellow and multiple colors appearing on a single specimen. It gets its common name from the knobs formed on the outer surfaces of both valves which resemble the paws of a lion. As a member of the Pecten family, they are edible as a scallop but do not occur in sufficient members to make them a reliable source commercially.
