Finding extents of Oracle BIN$ segments

I am looking for information on recyclebin extents. When dropping a table its segments are renamed to 'BIN$...' system generated names and the extents are hidden. Will those extents still stop me from shrinking a data file (or tablespace)? If so I would like to account for them in the script. Currently I am using a query inspired by AskTom's maxshrink.sql: select tbs.TABLESPACE_NAME, df.FILE_NAME, round(MAX(e.BLOCKS+e.BLOCK_ID+1)*tbs.BLOCK_SIZE/1024/1024,2) "MinMB", round(MAX(df.BYTES)/1024/1024,2) "FileMB" from DBA_TABLESPACES tbs LEFT JOIN DBA_DATA_FILES df on tbs.TABLESPACE_NAME = df.TABLESPACE_NAME LEFT JOIN DBA_EXTENTS e on df.FILE_ID = e.FILE_ID AND df.RELATIVE_FNO = e.RELATIVE_FNO -- WHERE -- tbs.TABLESPACE_NAME like 'MY%' GROUP BY df.FILE_ID, df.RELATIVE_FNO, tbs.TABLESPACE_NAME, tbs.BLOCK_SIZE, df.FILE_NAME ORDER BY 1,2; *Update*: Initially my question also asked why I no longer see the 'BIN$' segments created by Flashback Drop Table anymore in 12.2 anymore. However that was an error on my side, my test tables had simply no segments to begin with.
