By the way, a Cretaceous turtle and Ordovician trilobite were
found in separate drill cores in Florida.

In 1955, the Amerada Petroleum Corporation drilled wildcat well
12 miles northwest of Okeechobee, Florida. A well core from
9,210 feet contained the remains of a Cretaceous aquatic turtle.
The core, which was composed of gray argillaceous dolomite,
was 4 3/ 8 inches in diameter, recovered the anterior or front
end of it. Its skull and hind portions were outside the area of
the core (Olson 1965:4).

Further north, A similar chance recovery from a drill core was
made in Madison County, Florida. In 1944, the Hunt Oil Company
recovered drill core from depth of 4,628 feet. It contained a
Middle Ordovician trilobite (Colpocoryphe exsul) (Olson 1965:4).

The paper that describes and illustrates the Florida trilobite is:

In addition, a Paleocene mammal skull was recovered
from a depth of about 2,460 feet below the surface from
an oil well in Caddo Parish in Junior Oil Company,

"In the first of my notes, I speculated on the timing of

In the past, you have asked for my comments on this
feature, but I have been preoccupied with a geoarchaeological
study of the Louisiana Continental Shelf and Slope for the
Bureau of Ocean Energy Management, onshore geological
mapping, and other projects. Having just got back from the
field earlier than expected, I have had time to see what
has been pubished about the geology of the Kitscoty,
Alberta area in which this feature is located.

Fortunately, there exist decent, detailed geological maps of that
part of Alberta, e.g. Crickmay et al. (1942) and (Glombick 2014a,
2014b). Although there is an ovalish outcrop pattern, the
comparison of these geological maps to local topographic maps
found that this and other outcrop patterans are controlled by the
local topography. The best that I can find, the local structure
consists of gently dipping Cretaceous clastic strata that lack
any discernable uplifts or any other structure that can be
currently interpreted to be related to a major extraterrestrial
impact.

If a person looks hard enough anywhere in the world he
or she can find any number of enigmatic circular, oval, circular
and curvilinear features of uncertain origin illustrated in
Gableman (1984) that are not related impact structures or
craters. Of course, Gableman (1984) provides only one of
many explantions offered for these still mysterious features.

In slumming on the Graham Hancock Messageboard, I have
become aware of him. Randall and Graham seem to be kindred
souls in being contrarians and independent investigators into

overlooked by convential science and labeled either "alt-history"
and "alternative history." Some people, whom I know have far
less diplomatic and kinders lables for their interests.

Randall regards himself as self taught expert in whole range
of subjects, including geomythology, geology, catatsrophist,
planetary geologist, scared geometry, and so forth and an able
teacher of all the above. People can judge for themselves
how well Randall's self-evaluation of his expertise either
matches or mismatches reality by listening or reading his

It appears that this book has a quite different view of the
Younger Dryas Impact hypothesis than has appeared in the
"Proceedings of the National Academy of Science of the United
States" and other journals. This book appears will be not at
all helpful, as assumed by some people, at making their ideas
known among the public in a constructive manner. It might
end up as a classic case of be careful what you wish for as you
might get it. It will be very interesting to see how it all eventual
turns out.

Ed also stated:

"To my knowledge, the FIRST suggestion that the YD
impacts may have triggered a release of Glacial Lake
Missoula was made by me to the meteorite list several years
back in regards to Assiniboine memories of what occurred."

The latest megaflood from Glacial Lake Missoula has been
very intensively research. At this point, there is absolutely no
need to invoke an exterestrial impact for the latest Missoula

documented in numerous publications. For example, go see:

documents there having been at least over 40 to over a 100
separated Missoula floods having occurred over the last 1.5
millian years. Missoula-like megafloods definitely occurred
at least more than 780,000 years ago. As a result, a person needs
to explain how the latest Missoula Floods differs the other more
than 40 to 100 other Missoula Floods, which have occurred in the
past, that an extraterrestrial impact is needed to explain it.

New Paper About Bloody Creek Structure, Nova Scotia

New Paper About Bloody Creek Structure, Nova Scotia

There is a new paper about Bloody Creek structure. It is:

Spooner, I., P. Pufahl, T. Brisco, J. Morrow,
M. Nalepa, P. Williams, and G. Stevens, 2015, The
North structure: evidence for a second possible
impact event at the Bloody Creek site, Nova Scotia,
Canada. Atlantic Geology, vol 51, pp. 44-50.
DOI: http://dx.doi.org/10.4138/atlgeol.2015.002
https://journals.lib.unb.ca/index.php/ag/issue/view/1723
https://journals.lib.unb.ca/index.php/ag/article/view/22375

“The North structure is a discontinuous, partially
flooded elliptical basin 250 m in diameter and
defined by arcuate scarps. It is located in Annapolis
County, Nova Scotia, approximately 1 km north of
the Bloody Creek structure, a possible 400 m-diameter
elliptical impact crater.”

“What is lacking from the North and Bloody Creek
sites is a convincing petrographic record of shock
metamorphic effects, a problem that clearly needs
further investigation.”

“Both structures are interpreted to be post-Pliocene
(<2.6 Ma), based on the unlikelihood of their preservation
during Cretaceous-Paleogene regional peneplanation.”

They also note that preservation of pre-Pleistocene
saprolites beneath glacial tills as thick as 1–6 m at
locations within 10 km of the proposed suggests that
glacial erosion processes were not uniform in the
region of both landforms. alternatively, they argued
the “…well-preserved scarps and low depth-diameter
morphometry…” of these features “…might possibly
be the product of impact onto thin, stagnant glacial
ice…” 14,000 to 12,000 calendar years ago.

They conclude that much work remains to be done.
