Weird Objects in DBA_SEGMENTS

I have spent the morning cleaning out a tablespace in an attempt to
reclaim 800 GB of space and clean up my production data warehouse.  To
this end... I ran a BUNCH of 

 

ALTER TABLE <table> move tablespace <tablespace>;

 

It "appeared" clean... nothing in dba_tables or dba_indexes.

 

However, my life can't be that simple.

 

The paranoid dba on my left shoulder urged me to look at dba_segments...
so I did.

 

select owner, segment_name, partition_name, tablespace_name,
segment_type from dba_segments  where tablespace_name = 'STAGEDAT01';

 

there are a bunch of segments named similar to 

 

BIN$Rxl0mZVtGWjgRAADupYzGQ==$0

 

They "apparently" are tables and indexes.

 

There are, however, apparently no actual extents... because 

select * from dba_extents where tablespace_name = 'STAGEDAT01';

returns only the plan table that I want to drop anyway

 

anyone have any ideas on what these BIN segments are?

 

Thanks in advance.
