It's my impression that it's for better and easier ways to navigate our GIANT database of info. Tags are an easy way for the 'search' option to work.

jpc Posted November 30, 2016 Share Posted November 30, 2016 Yeah, if you need to get rid of fossils without labels, count me in. Nice crabs, by the way. Link to comment Share on other sites More sharing options...
Mike from North Queensland Posted November 30, 2016 Share Posted November 30, 2016 Nice crab preservation. These I assume are either a beach find or direct out of the local river bank. Have you tried looking for information on the current crabs from the area. A lot of the similar material that is found near me is not that old and still alive in the area.

Mike from North Queensland Posted December 3, 2016 Share Posted December 3, 2016 I do not know what they are but looking at the photos the male crabs have one claw larger that the other and this would be to attract a mate. Based on this I would say they are from a tidal environment not deep water. Mike D 1 Link to comment Share on other sites More sharing options...
JohnJ Posted December 3, 2016 Share Posted December 3, 2016 Maybe some species of Uca.... 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
ynot Posted December 3, 2016 Share Posted December 3, 2016 There are a lot of "fiddler crabs" in the tidepools of the California coast, could they be fiddler crabs?

PRK Posted December 3, 2016 Author Share Posted December 3, 2016 As a rule, I basically only identify the classification of a life form down to the generic level. I find without "expert" help the specific (special) ls soo detailed and varied, name is usually incorrect. Therefore I'm only interested in the general (generic) ID anyway. Of course there are always exceptions to every rule. so genus would be sufficient, but hey! PS, I'm from SoCal I've not seen those fiddle crabs down there, I think there relatively tropical Link to comment Share on other sites More sharing options...

Pagurus Posted December 4, 2016 Share Posted December 4, 2016 The rectangular shape of the carapace certainly resembles that of the fiddler crabs, of the genus Uca. It might be a good place to start, anyway. Maybe something in the family Ocypodidae, which includes Uca and the "ghost crabs". We have lots of fiddlers in the marshes around here in the north atlantic, probably a little more in the mid-atlantic. Names like Uca pugilator and Uca pugnax both refer to the habit of the males waving their big claws in the air, a little like boxing gloves, I suppose. I have no idea how long the genus has been inhabiting our big rock but it might be a reasonable trail to follow. I'm sure there must be other crabs with a similar-shaped carapace though. Good luck. Start the day with a smile and get it over with. Link to comment Share on other sites More sharing options...
