Mosquito’s Last Supper
New Acquisitions from
the 2013 Denver Gem &
Mineral Show
Eocene Mosquito’s Last Supper — A Mineral Sciences/Paleobiology Collaboration
If you haven’t heard the news yet, there is
a buzz circulating in the scientific community
about a recent discovery that took place in the
Smithsonian’s Departments of Paleobiology
and Mineral Sciences. The uproar is about a
small fossilized female mosquito found in
Middle Eocene (46 mil-
lion years ago) shale
from northwestern
Montana. What is so
intriguing about this
particular mosquito is
that it died and was pre-
served after having a
recent meal. Dale
Greenwalt, a retired
biochemist who collects
and analyzes insect fos-
sils from Montana for
the Smithsonian Institu-
tion, made the initial
discovery. Mr. Green-
walt wondered if the
abdomen of the fossil-
ized mosquito was en-
gorged by blood. Elicit-
ing the help of staff
geologists Yulia Goreva, and Tim Rose and
post-doc fellow Sandra Siljeström of the
Department of Mineral Sciences, the group
sought to answer this “Jurassic Park-like”
mystery. Utilizing DMS’ ToF-SIMS (time-of
-flight secondary ion mass spectrometer) and
SEM (scanning electron microscope) the
group was able to detect high levels of iron
and evidence of heme-derived porphyrins, a
blood protein, in the mosquito's abdomen.
From this evidence, Greenwalt and his team
concluded that the Eocene mosquito did in-
deed have blood as its last meal.
News of the discovery spreaded quickly and
was picked up by several media outlets, in-
cluding the Washington Post, Associated
Press and the National Geographic. Stories
about the discovery are currently being pre-
pared by journalists from several foreign
countries. The results of this study are pub-
lished in the Proceedings of the National
Academy of Sciences, volume 110, pages
18496-18500. Those with a subscription to
this journal can get access to the paper online

NPR and can be heard at http://

in-a-fossil-remnants-of-a-46-million-year-old-
meal.

Awards & Grants
Glenn MacPherson was awarded a grant for $59,000 from the Grand Challenges program
(Unlocking the Mysteries of the Universe theme) to purchase a newest-generation X-ray energy
-dispersive analyzer for the Department of Mineral Sciences’ scanning electron micro-
scope. This new detector will increase the efficiency for X-ray area mapping by a factor of
nearly 10x. The electronics for the analysis system have already arrived, and the detector itself
is expected to be delivered in November.
Cara Santelli received 2 grants this past fall. NSF, Environmental Engineering Program -
Collaborative Research Grant: “Optimization of metal attenuation in biologically-active reme-diation systems”. This award ($177,807) is a collaboration with Colleen Hansel (WHOI)
to identify the most effective microbial species and nutrient conditions (e.g., organic carbon
and nitrogen composition) stimulating optimal Mn oxide formation and subsequent met-
al attainment in acid mine drainage treatment systems.
DOE, EMSL/JGI Grant: “Genome-enabled Investigations of the Role of Secreted Proteins and
Reactive Metabolites in Carbon Degradation by Pure and Mixed Ascomycete Fungal Commu-
nities”. Cara is a co-PI with Colleen Hansel (lead PI) to identify the pathways for carbon degra-
dation in a diverse group of ascomycete fungi, with particular attention to the role of secreted
proteins and small molecules. With this proposal, the full genomes of at least 6 different spe-
cies of fungi (organisms previously identified by Santelli and Hansel because they contribute to
the biogeochemical cycling of carbon and the remediation of metal polluted environments) will
be sequenced. The award gives Cara free sequencing and access to highly technical scientific
equipment and staff.

New Faces in DMS
Carla Rosenfeld recently finished her Ph.D. in Soil Science
and Biogeochemistry at the Pennsylvania State University
studying plant-soil interactions and their influence on heavy
metals in soils. As a postdoctoral fellow at the Smithsonian,
Carla will study the role of mycorrhizal fungi, which form
symbiotic associations with a wide variety of plants, in pollu-
tant mobility and bioavailability. To do this, Carla will collabo-
rate with Cara Santelli and Melissa McCormick (SERC) stud-
ying microbially mediated metal transformations in selenium-
contaminated acid mine drainage soils.
Alexandré (Lexy) Fowler is a new contractor
in the Department of Mineral Sciences, and is col-
laborating with Cara Santelli on geomicrobiology
research. Lexy is currently working on both fungal
genome studies, and researching the relationships
between fungal metabolisms and serpentine miner-
al weathering. She began working as a volunteer
in Cara’s lab before receiving funding for contract
work through Cara’s grants. Lexy has a BA in
Geological and Environmental Sciences from
Hartwick College and an MS in Geological Sci-
ences with a focus in Geomicrobiology from the
University of Connecticut. She recently published
a paper on Bahamian stromatolites, and has previ-
ously studied both modern and fossil coral reefs
on San Salvador Island, Bahamas. Lexy also
works as a freelance writer of scientific education
materials and curricula. She thoroughly enjoys
working in the Mineral Science Department, and
hopes to one day become a permanent employee at
NMNH.
Denver Gem & Mineral Show New Acquisitions
Two samples of volcanic
bombs (lava fragments that
are ejected from a volcano
during eruption) were recent-
ly acquired and added to the
Petrology Collection. The
bombs were collected from
Mt. Shadwell, Western Vic-
toria, Australia and shows the
common aerodynamic spin-
dle-shape that often develops
as the lava travels through the
air. These samples are the
first purchase for the rock
collection in the last 25 years. Top image: Spindle-shaped volcanic bomb. Bottom image:

The Division of Meteorites recently acquired a nearly whole stone and two fragments of
the Chelyabinsk LL5 chondrite meteorite, which fell on February 15, 2013. The hundreds of
kilograms of material that reached the earth’s surface resulted from a Near-Earth aster-
oid that entered our atmosphere with an estimated speed of 18.6 km/s (over 41,000 mph or
66 960 km/h), almost 60 times the speed of sound. With an estimated initial mass of about
10,000 tons, and measuring between 17 and 20 meters in size, it is the largest known natural
object to have entered Earth's atmosphere since the
1908 Tunguska event that destroyed a wide forested
area of Siberia. Due to its enormous velocity and
shallow atmospheric entry angle, the object explod-
ed in an air burst over Chelyabinsk Oblast, at a
height of about 23.3 km (14.5 miles, 76,000 feet).
The explosion generated a bright flash, producing
many small fragmentary meteorites and a power-
ful shock wave. The total kinetic energy before at-
mospheric impact was equivalent to approximately
440 kilotons of TNT, 20–30 times more energy than
was released from the atomic bomb detonated at
Hiroshima. The predicted close approach of a se-
cond asteroid, the roughly 30-metre 2012
DA14 occurred about 16 hours later; detailed analy-
sis of the two objects later determined that they
were unrelated to each other.

The International Association of Volcanology and Chemistry of the Earth’s Interior
(IAVCEI) General Assembly is held every few years in a city located on a volcanically active
area. This year, over 1000 volcanologists, geophysicists, and geochemists from 43 countries
convened in Kagoshima, Japan. IAVCEI meetings focus on efforts to mitigate volcanic disas-
ters, and encompass volcano monitoring, eruption forecasting, and research in volcanology and
related disciplines. Many presentations this year focused on the real-time acquisition of volca-
no monitoring data, as well as the use and improvement of databases and tools to handle such
large data sets.
Several members of the Department of Mineral Sciences attended the IAVCEI meeting, in-
cluding GVP personnel Benjamin Andrews and Brendan McCormick, DCO Postdoctoral
Fellows Marion Le Voyer and Christoph Popp, grad student Stephanie Grocke, and visiting
scientist Georg Zellmer, who all presented their most recent research. One important focus of
this conference was the development of new databases in volcanology. Benjamin Andrews
chaired a session on “databases in volcanology”, where he presented the new eruption database
from Smithsonian’s GVP, entitled “Volcanoes of the World 4.0”. In this same session, Bren-
dan McCormick also introduced his work on “A
new global database of volcanic gas emissions”.
The exciting scientific program was complement-
ed with a number of uniquely Japanese social
events, including tea degustation, calligraphy
lessons, and the chance to try a kimono and/or a
samurai costume. During the mid-conference
field trip, attendees were lucky enough to witness
Sakurajima volcano erupt (pictured on the right),
complete with a magnificent ash plume, ballistic
rocks, and flank shaking.
