First documented on Florida east coast in 1998. See article: https://jaxshells.org/urosalpi.htm
Sifted from a partially filled gallon zip-lock bag of shelly sand and sorted under a binocular scope. Over 60 species of marine mollusks were identified.
My wife and I watched this Bobcat for 10-15 minutes as it wandered around just inside the woods behind the house. Our views were better than the cell phone photos suggest.
Note the epipubic bones still in place on the pelvis in photo #3.
