"Missing Out-of-box List and Library templates in SharePoint 2010"

Missing Out-of-box List and Library templates which are given below:
 Announcements, Issue tracking, Links,Calendar,Discussion boards and some other list templates that i was looking for.

Anyways, to bring the missing templates back all i did was, activated some site and site collection features which were not activated by default and which were responsible to add these list\library templates to the create page.

Here is the list of Features to activate -

Site collection feature -

• SharePoint Server Standard Site Collection features.

Site Feature for Activate:

• Team Collaboration Lists (Provides team collaboration capabilities for a site by making standard lists, such as document libraries and issues, available.) 
• SharePoint Server Standard Site features (Features such as user profiles and search, included in the SharePoint Server Standard License.)
