Ancient Bulldozer ... Crab Tracks
Ancient Bulldozer ... Crab Tracks - well I was here!
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 like!
- 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 around lane
- 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.
