HMNS Unveils Ground-breaking Discovery: Soft Tissue from the Dinosaur Age!

Well, the news is out, and here’s the scoop. The Houston Museum of Natural Science is involved in the next great discovery in the world of paleontology. In the forests of Myanmar, scientists have unearthed several pieces of 99-million-year-old amber that contain some of the best-preserved prehistoric lizards ever found. These little creatures walked alongside Tyrannosaurus rex, but encased in fossilized tree resin, they seem perhaps days old. The skin and soft tissues, the color of their scales and even their tongues have all survived millions of years of geologic time.


HMNS unveiled these specimens the morning of Wednesday, March 30, as part of our newest exhibit, Amber Secrets: Feathers from the Age of Dinosaurs. This announcement follows a social media buzz created by a paper published in Science Advances, written by Dr. Juan D. Daza of Sam Houston State University and co-authored by Dr. David Grimaldi of the American Museum of Natural History, curator of the Amber Secrets exhibit. The paper outlines the significance of this incredible discovery, crucial to a deeper understanding of the ecosystems of the mid-Cretaceous.


Unlike most fossils important to paleontology that amount to little more than mineralized skeletons, these lizard specimens, measuring a half-inch to almost two and a half inches, offer tissue samples allowing scientists to get an intimate look at these extinct reptiles down to the cellular level. Using CT scanners and 3D printers, paleontologists can zoom in and reconstruct these specimens in high detail, creating fully articulated copies of these ancient animals for research.

The favorite of the collection is an ancestor of the modern chameleon. A curling tail and features of its skull suggest it may have fed and moved similarly, but were it preserved in rock, these details would have been lost. Through the golden lens of amber, this lizard, like the others, looks out at us from across the expanse of time.

These lizards aren’t the only rock stars of this exquisite collection of Burmese amber, also called Burmite. The collection opened Feb. 19 showcasing more than 100 specimens containing feathers, invertebrates, fungi and flora preserved with incredible detail. Using modern technology, paleontologists are learning more about the ecosystems in this cross-section of time than ever before. These faithfully-preserved samples of ancient life allow us to peer across deep time and discover proof that feathered creatures lived alongside Tyrannosaurus rex and Triceratops, and evidence that could explain the development of the relationship between angiosperms and pollinators. The solutions to scientific puzzles like whether dinosaurs had feathers and the exact era in which plant life began to develop flowers could be contained inside these beautiful gold-glowing fossils.


Don’t just read about these amazing discoveries online; come meet these time-travelers for yourself, and learn the secrets they have to tell in Amber Secrets: Feathers from the Age of Dinosaurs while there’s still time. Open now through March 26, 2017.

Tales from Tanzania: Making beer, wedding skirts & attaching to chameleons with the Irwq

DSCN1314See that guy? That is Martin, and today we visited his house. He is one of the chiefs of the Irwq tribe, the second largest group in Tanzania (after the Maasi).

The Irwq (which is nearly impossible for English speakers to pronounce because it requires a guttural sound) are agriculturalists. The traditional Irwq house is built into the ground, due to a slight conflict with the Maasi who believe that all of the cows in the world belong to them. The Maasi would come to the Irwq villages in the middle of the night to “reclaim” their lost cows. To compensate, the Irwq started building their houses into the ground as dugouts so that when the Maasi would look for the Irwq houses, none would be visible.

In 1974, the president of Tanzania said that the Irwq couldn’t build thier houses in this manner any more because it used a lot of trees, and he understood the need for conservation. To stop the conflict between the Maasi and the Irwq, the president declared if the Irwq could prove that their cows had been “reclaimed,” the government would give them 10 cows to replace it. This eliminated any hostilities between the two groups almost immediately.


Martin (our friend pictured above) is allowed to keep his house because he and his tribe teach traditional crafts and ways to the Irwq people (and a small group of HMNS travellers), somewhat like a museum. He taught us about two very important parts of his culture: beer making and wedding skirts.

The “local beer” is super important and is prepared before any big job, ceremony or wedding. To make it, corn is ground and mixed with yeast and cane sugar or honey. Finger millet is ground and added to this after a few days. It is then boiled and left to sit for two days. On the third day, it’s ready.

After trying the local beer, which I would say has the flavor of applesauce made from diluted vinegar, I think I will stick with Shiner.

The other skill Martin’s wife, Victoria, showed us was how to make a wedding skirt. The skirt is made from dried goat skins. Once the skin has been dried out, a special tool is used to scrape off the hair. The skins are then cut into wedge pieces and sewn into an apron shape, and beading is applied.


When Victoria asked for volunteers to try the beading, I hopped right up! Sewing is a skill I can get behind. The beading is similar in technique to Native American seed beading and every pattern has a meaning.


The blue river pattern, Martin explained, is a metaphor for life. The river goes up and down, just as life has ups and downs. In the rounded patterns at the bottom you can see the tree of life, and just above those you can see a gourd shape, which represents a calabash.

The colors have meanings as well. Yellow represents the natural resources and minerals, green for vegetation and black for the African people.

The best part of the visit happened in the last few minutes. Some of the village children were playing in the bushes and found a chameleon. Apparently the kids are taught that chameleons are poisonous (maybe to keep them from bothering them?), and I have heard a couple different versions of folk tales that say if a chameleon bites you, it won’t let go — and the chameleon becomes part of you. So the kids were willing to show us the chameleon, but from the far end of a very long stick.


We, on the other hand, had no such worries, and you can tell by Dave’s face that he was tickled pink to get to hold it.

So here’s what went down after you logged off.

The world’s most organized lizards: not only do members of the chameleon species Furcifer labordi  all hatch at the same time – they also manage to always do so in November. They then live for only four months – making them the shortest-lived, four-limbed vertebrates.

Penguins are dying – sounding the alarm over the health of the world’s oceans.

Scientists have compiled the first complete map of the human brain.

Today is the 150th anniversary of the formal presentation of the theory of evolution. Though it is often credited to Charles Darwin, NPR has an interesting story about whether his contemporary, Alfred Russel Wallace, deserves some of the credit.
