Ancient Bulldozer ... Crab Tracks - well I was here!
My Story - I'm not really here all that is left
behind is my tracks! I leave crabs tracks wherever I go.
110 million years ago in north western Queensland , Australia I crab dug
this burrow along a muddy / sandy shore of an ancient shallow sea .
My carb track is similar to modern crabs so while my body and
remains are no longer around you can take an educated guess at what I look
In a muddy bank it digs a curving hole down into the muddy sand.
It must back down the hole so there is a back up area and a turn
as the racks get used again and a again they get deeper
when the crab stops or rest you get a clear imprint of the bottom of
the shell or carapace.
As a crab I used this tunnel to keep out of the sun at low tide.and as a
safe place to retreat
Modern crab burrow similar in design of my crab hole so I must have look
about the same.
Modern crab carapace would leave an imprint in the mud like this and where
I sat you can see the imprint of my bottom!
Scale shows I was not a big crab. You can see the imprint of my "carapace"
(bottom) where the two tracks meet and where I crab rested!
Although no actual parts of me crab can be found , by comparing the tracks
to those left by modern day crabs you can confidently say these were
ancient crab track.
