This is a recurring theme in bug reports: it re-appears each time a new compression utility emerges. I doubt that a new long option should be added for each existing compression utility: after all `--bzip3` is no better than `-Ibzip3`. On the other hand, GNU tar had long ago run out of alphabet letters for use in short options. What can be done is to implement automatic recognition of bzip3 format for extraction and recognition of .bz3 suffix for archiving with `-a`.

I'll update this tracker if/when it is implemented.

GNU tar does not officially support bzip3, only up to bzip2.
This is not a bug, bug a feature request.
In the meantime the workaround is pretty simple:

tar -I bzip3 -xf calgary.tar.bz3

Tar does not recognize the bzip3 compression format. Here is how one can reproduce this error.

1. Download the attached file calgary.tar, and compress it with bzip3, using `bzip3 -z calgary.tar`. It will produce a file called calgary.tar.bz3
2. Try to decompress the file with tar only, for example `tar -xf calgary.tar.bz3` The following error results:

```
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
```
