Evidence of fossilized blood-feeding insects associated with mammal hosts include
a Pulex flea and an argasid
(“soft”) tick, each preserved with strands of very rare mammal hair
in Miocene amber from the Dominican
Republic. Here we report another very rare instance of a fossilized blood-feeding
association. From among
more than 100,000 pieces of Dominican amber we have found three pieces that
contain small swarms of the
phlebotomine genus Lutzomyia (family Psychodidae) with strands of mammal hair,
along with debris
presumably from a nest. Given the rarity of mammalian hair in Dominican amber,
the probability of finding
hair along with Lutzomyia based on chance alone is extremely remote. Thus, these
blood-feeding midges were
probably feeding on the mammal that shed the hairs, and some of the female midges
are even bloated,
presumably with a blood meal. Detailed maps of the pieces are presented, which
aid the taphonomic
interpretation of the assemblage. Pending the possible identification of the
hair based on fine structure, we
hypothesize that the phlebotomines were swarming and feeding around the arboreal
nest of the mammal host.
New World phlebotomines today harbour various pathogenic microbes, including
Leshmania, Bartonella, and
various trypanosomes,and given the remarkable cellular preservation in amber
it should be possible to
determine if these fossil Lutzomyia also harbored microbes that were pathogenic
to mammals."

Description
This is an auction for an Extremely
Rare Mammal Hair Strand along with a small cockroach in an authentic
Dominican Amber Gemstone . This specimen was excavated in the La Bucara
amber mines in early Spring of 2007. This specimen has been examined
by paleoentomologists at the American Museum of Natural History in New
York City. This is only our 3rd confirmed mammal hair in Dominican amber
and our first find in almost 5 years.

Dominican
Amber
In the Dominican Republic, Hymenaea trees are called Algorrobo. The Hymenaea
tree exudes vast amounts of resin which over millions of years of pressure
hardens into amber. Generally amber is found because a landslide along
a steep slope in the mountains exposes veins of black lignite. If the
lignite contains amber it is gradually extracted by digging along the
vein with picks and shovels. After the amber is found it is chiseled by
hand out of the shaft walls, put into burlap sacks and passed out of the
mine where it is separated from the rock by machete. Larger chunks of
amber make it possible to view inclusions almost immediately by holding
the amber up to sunlight to determine if a large inclusion has been discovered.
Fossil bearing amber is polished locally.To view photos and videos of

About Us
We have been collecting amber in the field and prepping rough fossil
amber specimens since 1993. Photographs of our specimens have appeared
in National Geographic, Nature, Science, Scientific American, Discover,
Time, Newsweek, The New York Times and others. We have been featured
in PaleoWorld's The Amber Hunters. We offer authentic museum quality
Dominican Amber display specimens of rare insects in amber and also
authentic rare Dominican rough unprepared amber for sale. Our collections
include museum quality rare insects in amber, unusual botanicals and
flowers in amber and also rough unprepared Dominican Amber gemstones.
We have traveled many times to the Dominican Republic where we have
chiseled beautiful amber gemstones out of the lignite layers deep in
the amber mines north of Santiago. We have excavated in the Palo Quemado
and Los CaCaos blue amber mines and also in La Nueva Toca and the world
famous La Toca amber mines way up in the mountains north of Santiago.
For many years we have extensively collected mid Cretaceous New Jersey
amber in the Raritan formation of central New Jersey and have traveled
many times to collect late Cretaceous and early Paleocene amber in the
Hanna formation of eastern Wyoming. We have collected mid Cretaceous
amber in the Black Creek formation of eastern North Carolina and we
have spent weeks collecting mid Cretaceous amber in the northern most
Tundra of Alaska. Some of our most recent collecting trips have been
in October of 2003 to the western Aleutian Islands some 1000 miles west
of Anchorage to explore and collect Miocene amber, August of 2004 and
April of 2006 we were back in the Dominican Republic to collect Miocene
amber from the Palo Quemado amber mines which have recently closed due
to the miners finding little amber, we were back to the Dominican Republic
in April of 2006 to video in the La Toca amber mines, and most recently
in August of 2007 we excavated in La Toca and La Bucara. The La Toca
amber mines had much water whereas on the other ridgeline the La Bucara
amber mines were nearly dry! We collected much amber from both La Toca
and La Bucara.
We have donated many hundreds of amber specimens to museums in the United
States and have several dozen new species of insects in amber named
after us. We have examined several thousand specimens of rough Burmese
amber and have prepped many new Burmese fossil amber specimens. We have
traveled to Europe with colleagues to examine unusual spectacular Dominican
Amber specimens in private collections and we consider the amber curators
of the museums in Santo Domingo, Puerto Plata and New York City our
friends. Exploring for and collecting amber along with the examination
and research of amber is our passion.

the amber mines in mountains of the Dominican Republic and to see a

the Dominican Republic amber mines east of the world famous La Toca
amber mine. These specimens do not go through any middle men, we acquire
these specimens from the miners and mine owners directly at the amber
mines.
