You need to query your dataset with a metadata query.

SELECT * FROM publicdata:samples.__TABLES__ 
WHERE MSEC_TO_TIMESTAMP(creation_time)  < DATE_ADD(CURRENT_TIMESTAMP(), -7, 'DAY')

this returns

+-----+------------+------------+-----------------+---------------+--------------------+-----------+--------------+------+---+
| Row | project_id | dataset_id |    table_id     | creation_time | last_modified_time | row_count |  size_bytes  | type |   |

You can add in the WHERE clauses to restrict to tables similar to

• WHERE table_id contains "wiki"
• or regexp like WHERE REGEXP_MATCH(table_id, r"^foo[\d]{3,5}")
