100 Years – 100 Objects: Egg Mass

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 on hmns.org – throughout the year.

A rarely seen egg mass of Murex pomum Gmelin, 1791 is the result of communal cooperation.  By joining together with other females to deposit their eggs, the protection afforded to the unborn is greatly increased.  Not only is there security in the large numbers for the newborns, but the mass is also a more formidable whole to repel determined predators. 

These impressive structures are accomplished by numbers of females ranging from two or three adults to twenty or more. 

This egg mass was found washed ashore on a beach on Sanibel Island, Florida, USA.

100 Years – 100 Objects : Elbaite (on Quartz)

This description is from Joel, the Museum’s President and Curator of Gems and Minerals. He’s chosen spectacular objects from the Museum’s mineralogy collection, which includes some of the most rare and fascinating mineral specimens in the world, that we’ll be sharing here – and on hmns.org – throughout the year.

North America has produced some extraordinarily beautiful specimens of elbaite, a member of the tourmaline group, but the most admired are the bright red-pink crystals with blue caps found in 1972 at the Tourmaline Queen mine. The 24-cm example pictured here is the finest of the 33 major specimens recovered and is therefore the finest North American tourmaline. The lustrous, lusciously colored, undamaged pair of crystals at the top grow from an undamaged quartz crystal and are accompanied by smaller tourmaline crystals. It has been nicknamed “The Rabbit Ears.”

100 Years – 100 Objects: Manatee Ribs

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 on hmns.org – throughout the year.

These bones, part of the Attwater-Westheimer collection, represent the fourth specimen record of Manatee (Trichechus manatus) for the state Texas.  They were collected prior to 1929 at San Jose Island, Aransas County. 

For years they were passed over as part of a ‘vat of dolphin [Tursiops truncatus] bones’ which Attwater probably collected on the beach at San Jose Island concordant with collection of disarticulated dolphin skeletons. 

This finding was important enough for HMNS staff to publish (2001. Tx. J. Sci. 53: 292-294).

100 Years – 100 Objects: Giant Armadillo

This description is from David, the museum’s associate 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 on www.hmns.org – throughout the year.

The armadillo is an iconic animal in Texas, and this relative of the smaller, modern forms takes “Texas-sizing” to the extreme. This species, commonly known as Giant Armadillo, would have been nearly 6 feet long and weighed nearly 500 pounds. Like its modern cousin, this ancient animal was an immigrant to North America from the south, slowly migrating northward and subsisting of a diet of mostly plants and perhaps insects. The giant armadillo roamed and rooted along the Gulf Coast and as far north as southern Oklahoma, but disappeared about 10,000 years ago.

The Museum’s Giant Armadillo is a Houston fossil, discovered in 1955 by Florence Dawdy, a teacher, with her school age son and a friend near the old Scott Street Bridge on Brays Bayou.  Her family’s curiosity and concern about the fossil brought the find to the attention of the geology department at the University of Houston. This decision saved the fossil from further erosion or looting. UH students and volunteers excavated the fossil and provided the initial curation. It was described as part of a Masters Thesis at UH and then later published by Gideon James in the Journal of Paleontology, Vol. 31, No. 4, pp796-808, July 1957, An Edentate from the Pleistocene of Texas.

For over 30 years, the Museum’s Giant Armadillo was the best example of Holmesina septentrionalis known to science, and it is still one of the most complete.

The Giant Armadillo was given to the Museum by the University of Houston and was mounted by proceeds raised from the Museum’s 1991 armadillo-themed Guild Gala. The specimen was mounted in two dimensions as a plaque, so visitors would experience the fossil as it was originally found.
