OU R DI PL OD OC U S R E T U R N S HOM E! After a long spa treatment, the signature dinosaur of the Houston Museum of Natural Science—the Diplodocus hayi— has returned home to take her spot in the limelight of the Morian Hall of Paleontology.

“Her” you ask? It is believed D. Hayi is a female because she has gashes in her hip bones which could be mating marks.

A Diplodocus nonhai kept D. Hayi’s spot warm for her in the new hall, while en route to her new home in a shopping mall in Dubai. You can stop by and give her a big Texas “howdy” if you make it for a visit.

If her story is not dramatic enough, D. Hayi is also having an identity crisis. Although classified as the holotype specimen for Diplodocus hayi, this April a group of scientists have proposed to reclassify D. Hayi as a new species that will be called Galeamopus hayi.

When her roommates moved to the new Dan L Duncan Wing, D. Hayi traveled to Wyoming where she underwent an extreme makeover. She has had two previous extreme makeovers after moving to Houston from Pittsburg in 1962. Her bones were originally on display lying on a platform before she was erected by John Barber in 1975. When new evidence was discovered that she must have certainly walked with her tail up high, a tail lift was the order. D. Hayi is now styling a new modern pose—her tail lowered to help balance her girlish figure while she is standing on her hind legs nibbling on the highest tree branches.

H M N S C H I N A ' S L O S T C I V I L I Z AT I O N : T H E M Y S T E R Y O F S A N X I N G D U I

The artifacts on display cover two locations and a period of about 1,000 years, from around 1600 BC to 650 BC. They tell a tale of two cities, Sanxingdui and Jinsha, both located in the modern province of Sichuan in southwestern China. To paraphrase Winston Churchill, their story is one of a riddle wrapped in a mystery inside an enigma.

A lack of written sources directly associated with these two sites prevents us from clearly identifying who built the cities and dug the sacrificial pits encountered there.

Some thirty miles away, the ancient site of Jinsha revealed a similar array of material culture. Dating to a period between 1000 and 650 BC, it is more recent than Sanxingdui. It may have served as a home for Sanxingdui citizens who abandoned their city around 1100 BC. A clear answer to why they did so is still missing, although there are plenty of suggestions.

A lack of written documents notwithstanding, Sanxingdui and Jinsha clearly demonstrate that the traditional idea of a core area of Chinese civilization needs to be revisited.

Archaeologists widely accepted that Chinese culture arose in the Yellow River Valley in Northern China. The sophistication of the Sanxingdui culture has forced archaeologists to take a new look. That is what makes this exhibit so fascinating: we get a close look at a long lost culture.

On a rare tour outside of China, this exhibition features larger-than-life bronzes, jades, gold objects, ceramics, ivory and sea shells from both the 1986 Sanxingdui excavation and the more recent 2001 Jinsha excavation.

Sanxingdui, China’s Lost Civilization is organized by the Bowers Museum, Santa Ana, California; the Houston Museum of Natural Science; and the Cultural Relics Bureau of Sichuan Province, Peoples Republic of China.

Major funding has been provided China Southern Airlines with local support provided by Kathrine G. McGovern/ McGovern Foundation.

DISTINGUISHED LECTURE “Unmasked: Mysteries of the Ancient Shu Kingdom and its Bronze Art” Liu Yang Minneapolis Institute of Arts Tuesday, June 2, 6:30 p.m.

Most astonishing of the finds of Sanxingdui are the bronze humanand semi-human masks showing fantastic features with large eyes with projecting pupils, strongly curled nostrils and tightlipped mouths. Several are covered in gold. Did these figures represent deities, ancestors, priests or shamans? Sharing the ritual practice and symbolism hidden behind these false faces, Dr. Liu Yang will provide a fascinating look into the mysterious Sanxingdui culture and the masks of mystery.

BEHIND-THE-SCENES TOUR “The Bronzes of Sanxingdui” Tuesday, May 19, 6:30 p.m.

Tickets $37, Members $27

www.hmns.org/exhibits

What we currently know is this: around 1600 BC, Sanxingdui was a city covering about 1.5 square miles.

Located on the banks of the Jian River, Sanxingdui was a walled city.

Archaeologists identified workshops, a

residential area for commoners as well as the elite, and an area where sacrifices may have occurred. Two large pits were found at Sanxingdui; both contained jade and bronze artifacts, Asian elephant tusks, animal bones and shells.

H M N S C H I N A ' S L O S T C I V I L I Z AT I O N : T H E M Y S T E R Y O F S A N X I N G D U I

Being an archaeologist is a fascinating profession. The study of tangible remains from the past helps us understand what people were doing in a given place at a certain time.

The exciting part is that discoveries are made on an almost daily basis.

Sometimes these discoveries confirm what we already know, but occasionally they gently nudge us to abandon the comfort of traditionally accepted wisdom, and rewrite our textbooks.

China’s ancient site of Sanxingdui exemplifies the latter, and relics from that unique culture now on exhibition at HMNS will show you how.

Samurai lived by the Bushido code.

“The Way of the Warrior”—the meaning of “Bushido”—encompassed a combination of frugality, loyalty, martial arts mastery, and honor unto death. Prevalent during the Tokugawa Shogunate (also called the the Edo period), the code shaped samurai lives.

While the Edo period was primarily a time of peace, the samurai felt that it was their duty to be ready to serve.

They continued to invest in armor to wear in fighting for their master whenever summoned. For more than two centuries, they waited in vain.

As a result, their armor remained in almost mint condition. When change finally did occur in the middle of the 19th century, the world of the samurai

came to a dramatic end. They lost their privileged position in society, and were eventually forced to sell their prized possessions in order to survive. Some of these outfits were collected by Anglo-Italian financier Federico Stibbert. Part of his extensive collection is now on display at HMNS. Samurai warriors resplendent in their colorful armor now stand guard in Houston, awaiting your visit.

Samurai: The Way of the Warrior will be on exhibition in Houston through September 7, 2015. This exhibition is organized by Contemporanea Progetti SRL with the Museo Stibbert of Florence, Italy. Local support is provided by Kuraray.

Kyoto, Japan. John Seavitt will provide commentary during the silent ceremony.

Guests will receive tea and sweets following the demonstration and lecture.

The Texas coast is a natural treasure to many Texans, but few know about its ecologic and economic importance.

The Hamman Hall of Texas Coastal Ecology will show visitors how a healthy environment is paramount to maintaining and sustaining a healthy economy.

Adjacent to the new Farish Hall of Texas Wildlife, this hall completes the story of our great state’s flora and fauna. HMNS visitors will learn about the environmental characteristics of the Texas coast, as well as critical habitats, iconic species, concerns and impacts, recreation, and opportunities for conservation and restoration.

The hall showcases the three distinct areas of the Texas coastline: upper coast, middle coast and lower coast.

The upper coast—in Houston’s backyard—stretches from the Sabine River to Freeport. This region is characterized by plentiful freshwater inflows and dominated by salt marsh and oyster reef habitats.

From Freeport to Aransas Bay, the signature of the middle coast is nesting shore birds. In this area of the exhibit, the story of the brown pelican, a conservation success story, will be highlighted The lower coast, from Aransas Bay to Brownsville on its southern end, is

WHO’S WHO IN THE HONEY BEE HIVE QUEEN BEE Each colony is “ruled” by a single queen. The pheromones produced by this amazing individual keep the colony running smoothly. Her only job is to lay the eggs that grow into the workers and drones. The sperm she receives during her nuptial flight, usually from multiple drones, will be enough to fertilize the millions of eggs she lays in her two to six year lifespan.

During the spring, she can lay up to 2,000 eggs a day. Unlike her worker bee daughters, a queen bee is able to sting multiple times. She normally only uses her sting to kill rival queens when starting up a colony.

WORKER BEES Most of the eggs laid by the queen produce sterile female worker bees.

These workhorses of the colony live only a few weeks, and during that short time perform all the tasks that keep the colony running: building the wax comb, caring for the eggs and larvae, bringing in pollen and nectar to make honey, and defending the hive. In her lifetime, a single worker bee makes only about a twelfth of a teaspoon of honey. For every pound of honey made by the hive, these busy creatures visit

approximately two million flowers and travel seven million miles! Forager bees returning to the hive tell their sisters where to find good nectar sources by doing a special “waggle” dance. People fear bees because of their sting, but since her sting is barbed, a worker bee can only sting once, losing her life after stinging – so stings are used judiciously, usually only when the hive is threatened.

DRONES The word “drone” means a lazy mooch and with good reason. The only job male honey bees perform is to mate with new queens. When a virgin queen flies out on her nuptial flight, she is pursued by dozens of eager drones, all racing to catch and inseminate her – only the strongest and fastest will succeed. The winners die after mating.

Drones that remain in the hive after the mating season are often driven out by the workers, especially before winter when resources are scarce.

Burke Baker Planetarium DISTINGUISHED LECTURES “Climate and the Demise of Maya Civilization” André Droxler, Ph.D. Rice University Tuesday, June 16, 6:30 p.m.

H M N S B U R K E B A K E R P L A N E TA R I U M

New evidence and data is revealing that climate conditions influenced the destiny of the Mayan civilization.

Geological data from Belize’s Central Shelf Lagoon and Blue Hole, areas proximal to where Maya Civilization thrived and then abruptly collapsed are revealing that weather—rainfall fluctuations and frequent tropical cyclones—may have forced the Maya to abandon their sophisticated cities.

www.hmns.org/planetarium

Maya cities on the Yucatán Peninsula reached greatness in relative isolation, in a tropical climate with no large rivers—a land that depended on annual rains for water. The people of these cities dug cisterns to store water, and developed writing, mathematics, and astronomy to measure the passage of time, to predict seasonal rains, and to manage resources.

In the last five years, researchers have amassed sediment data from sources that include lake bottoms, stalactites in caves, coastal lagoons, and underwater sinkholes. These deposits are affected by many environmental factors including the amount of rainfall or, in the case of the sinkhole, the frequency of tropical cyclones. This research indicates that the Yucatán Peninsula experienced the most serious droughts in a thousand years during the period from 800 to 900 AD—the time of the collapse of the Classic Maya civilization.

We now realize that these droughts were caused by the location of the

Intertropical Convergence Zone (ITCZ), a band of clouds, rain, and storms that normally reaches the Yucatán each summer. But if the Northern Hemisphere is too cool, this zone will stay south of the Yucatán and drought will follow.

In Fate of the Maya, you can visit the great Maya cities of Caracol, Uxmal, Chichen Itza, Palenque and Tikal to see how astronomers predicted the annual rains and the population flourished. Then we see natural events, new evidence, and direct effects of the global climate fluctuation that caused the Maya collapse.

What will you learn in the treehouse?

Trees provide habitats for many different animals that can leave identifiable traces behind, such as foot prints, scratch marks and scat. Some animals have adapted to life in the tree.

Trees are used to make many different products in our lives: houses, drink, and foods such as nuts, fruit and chocolate.

We can all be good environmental stewards by planting trees and logging sustainably. Trees sustain life on Earth.
