New Dinosaur Exhibit Features Field Site Total Immersion in Scientific Discovery

Link between Ancient Blood-Sucking Bug and Disease-Causing Parasite Reported in Vector-Borne and Zoonotic Diseases

----A sample of
Dominican amber, around 20 million years old, has provided the first
fossil evidence that Triatoma dominicana, a large blood-sucking bug,
was a vector for the transmission of Trypanosma antiquus, a
disease-causing protozoan parasite related to the microorganism that
causes Chagas disease, as reported in the Spring 2005 issue (Volume 5,
Number 1) of Vector Borne and Zoonotic Diseases, a peer-reviewed
journal published by Mary Ann Liebert, Inc.

"We're
always looking for new approaches that the field as a whole can benefit from
in terms of improving public understanding of science. The juxtaposition
of these findings suggests that the bug excreted the protozoa in its
feces prior to fossilization.

Opening Saturday, May 28, the exhibit gives children and their families
the chance to use the skills and tools of paleontology in a dynamic, 8,000-
square-foot space featuring a quarry-like field site, laser technology,
multimedia computer laboratory, documentary videos and loads of bones from the
Lone Star state. The other is the first nearly complete skeleton of a large
four-legged plant -eater, temporarily known as Pleurocoelus, found on a ranch
in Hood County by students at the University of Texas. Scrutiny of amber specimens proves to be a
fascinating and productive endeavor, worthy of encouragement.

It is expected that Lone Star

triatomines has been a controversial and debated topic, primarily due
to the lack of any fossil evidence. The finding of
fecal droplets adjacent to the specimen and containing fossil
Trypanosoma cruzi-like trypomastigotes is beyond all expectation and
lends circumstantial support to the notion that bat Schizotrypanum

Located near the fecal droplets were mammalian hairs, identified

that triatomines are very recently evolved from predatory Reduviidae,
another, in part based on molecular phylogenetics, that triatomines
and the blood sucking life style are older.D., from the Department of Pathology, University of
