Shamalama Posted February 25, 2010 Share Posted February 25, 2010 Where from, what age, and do you have better pics? :D -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

orangebuccaneer Posted February 26, 2010 Author Share Posted February 26, 2010 this fossil is the oldest insect trace fossil found in awhile....I can't give too much info secret location but a beautiful specimin Link to comment Share on other sites More sharing options...
JohnJ Posted February 26, 2010 Share Posted February 26, 2010 As Shamalama mentioned, it would be easier to see your "beautiful" specimen with larger photos that include a size reference. Some may not know what a "bristletail" is, and giving the geologic age shouldn't compromise your secret. <...looks like a dugong footprint, right now > The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Auspex Posted February 26, 2010 Share Posted February 26, 2010 Do I understand correctly that this is the imprint left by a bristletail when it landed on, or departed, a muddy surface?

ashcraft Posted February 26, 2010 Share Posted February 26, 2010 Bristletails (order Thysanura), are the most primitive group of insects still living. They include the common silverfish, found in damp spaces around your house. They are wingless, and may represent the branch where divergence occurred from the winged insects (not insects that secondarily lost their wings, such as fleas). They are known from the fossil record, primarily by their distinct "footprint", as seen in the fossil shown. Depending on the age of the rock where found, it may shed light on the evolutionary history of the insects. At least that is what I recall from entomology class.

Depending on the age of the rock where found, it may shed light on the evolutionary history of the insects. At least that is what I recall from entomology class. Brent Ashcraft In "Evolution of Insects" (Grimaldi and Engel, 2005) there is no mention of bristletail prints and really no mention of fossil insect tracks (though other ichnofossils are discussed), so if such fossils have been otherwise documented, that represents at least a minor breakdown in the coverage of insect remains for the book. It does note that the oldest insect fossils from North America are two segments of a bristletail from the Middle Devonian of Quebec (Gaspe beds). It would be very interesting if Orangebuccaneer's track is from an older site in North America or perhaps even older than the Early Devonian Rhynie Chert of Scotland from which a few arthropod fragments have been officially reported as the earliest known insect (Rhyniognatha).

Auspex Posted February 27, 2010 Share Posted February 27, 2010 Interesting topic! (I love ichnos, ask anyone). Anybody have access to more on this: >SEE LINK< ?

flyguy784 Posted February 27, 2010 Share Posted February 27, 2010 Better pictures would be nice. My guess would be, late Triassic early Jurassic mudstones of the Newark Group. I think I recognize a worm hole just below and to the right of the insect impression. Very nice ichno, regardless. Don't forget the scale. If my guess is correct, a quarter would cover the impression. Link to comment Share on other sites More sharing options...
orangebuccaneer Posted March 4, 2010 Author Share Posted March 4, 2010 from my understanding it older than 350 million yo and its a relative from the the bristletail i will post a pic with a quarter i found it in plainville ma Link to comment Share on other sites More sharing options...
dhk Posted August 3, 2010 Share Posted August 3, 2010 Hi, the site is easy to get to. I find amphib and insect tracks almost every weekend. Lots of plants as well. Any interest??? Link to comment Share on other sites More sharing options...
