100 Years – 100 Objects: Seed Fern

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 David Temple, the museum’s curator of paleontology. He’s chosen a selection of objects that represent the most fascinating fossils in the Museum’s collections, that we’ll be sharing here – and at 100.hmns.org/ – throughout the year.

Seed fern, Alethopteris grandini
(Pennsylvanian, Stranger Formation, Franklin County, Kansas)

CHI_7671Vast swamps covered many parts of the world during the Pennsylvanian Period. The plants that grew in them included ferns, seed ferns, rushes, and tree-like lycopods with scaly trunks. When these plants died, they settled into stagnant, oxygen-poor water, in which their carbon was eventually preserved as coal. Among these coal swamps lived many kinds of amphibians, the first small reptiles, many types of insects and other arthropods such as large cockroaches, giant dragonflies, millipedes and scorpions.

This description is from Nancy, the museum’s director of the Cockrell Butterfly Center and curator of entomology. She’s chosen a selection of objects that represent the rarest and most interesting insects in the Museum’s collections,that we’ll be sharing here – and at 100.hmns.org- throughout the year.

Madagascar Sunset Moth – Chrysiridia rhipheus

Madagascar Sunset Moth-6x5This spectacular, iridescently colored moth is considered by many to be the most beautiful of all Lepidoptera (the order of “scaly winged” insects, i.e., butterflies and moths). A day-flying moth endemic to Madagascar, it was originally described as a butterfly due to its resemblance to the swallowtails. The rainbow of colors on both upper and lower wing surfaces that make this species so sought after by collectors are not due to pigments, but result from the scattering and reflecting of light by microscopic ridges and pits on the highly curved scales covering the wings.

The museum has several hundred specimens of this moth.  It is relatively common in its native habitat, where it periodically undergoes massive one-way migrations when the hostplants for the caterpillar stage (they feed on trees in the spurge family) increase the amount of distasteful toxins in the leaves.  Interestingly, after the migration has lessened pressure on the hostplant, the amount of toxins in the leaves subsides to normal levels.  In the American tropics, a close relative, the green Urania moth (Urania fulgens), also makes mass migrations for the same reason.

CHI_4646 - cropThis description is from Dirk, the museum’s curator of anthropology. He’s chosen a selection of objects that represent human cultures throughout time and around the world, that we’ll be sharing here – and at 100.hmns.org - throughout the year.

Bodmer print showing American Indian dancer

When studying American Indian culture, the drawings made by Karl Bodmer (1808-1893) are of great importance. This Hidatsa warrior is wearing a headdress identifying him as a member of the Dog Soldier Society. Items like these provide us with context, essential to come to a better understanding of the objects in the collection. In this case, the print is on display next to a case holding a similar headdress.

Trilobites, Homotelus bromidensis
(Ordovician, Bromide Formation, Criner Hills, Oklahoma)

CHI_7593First appearing 530 million years ago during the Cambrian Period, trilobites flourished in shallow seas for 290 million years, placing them among the most successful of early complex life forms. Today, fossilized trilobites are popular with collectors because they are abundant, often well preserved, and occur in a wide variety of forms.

Trilobites were among the first animals to have hard body parts and easily recognizable eyes. While most trilobites were on the order of several centimeters long, a few species reached lengths of over half a meter.
