Try the following:
set echo on
column segment_name format a30
column tablespace_name format a15
column owner format a15
select tablespace_name, owner, segment_name, bytes/1048675 SizeM
from dba_segments
where (tablespace_name, bytes) in (
select tablespace_name, max(bytes)
from dba_segments
group by tablespace_name
This will find the largest segment. If you want to limit it to tables then add another where clause condition on segment_type = or in the types you are interested in.
You can find dba_segments described in the Oracle version# Reference manual along with all the Oracle rdbms dictionary views.
