In May 2018 UNSW Embryology reached a landmark of more than 4,000 content pages and more than 15,000 uploaded files.

Current total number of topic pages - 6,446

This current page contains links to content pages that have been recently updated or added to this site. Please note that not all site updates are logged on this current page.

UNSW Embryology has now been available online and continuously updated for 21 years!

Since software updated to MediaWiki 1.26.2 the total number of page views magicword is no longer supported. Therefore I cannot continue to provide view count updates from 2016 onwards. Individual pages will also no longer show "number of views" in the footer. 10 Popular Pages below is based upon pre-2016 data.

10 Popular Pages

OK these are not my rankings, but by you the viewer.

These are the top ten popular pages based upon page views.

I have excluded the Main page, student projects and undergraduate course pages. Note, this data has not been updated since 1 January 2016, when page visit logs were removed.
