What is a cladogram:

  • A cladogram is an infographic that shows the relationships of scientific taxa. These can be useful to show how animals are related in almost any article on organisms.

What can have a cladogram:

  • Any article with enough information in the literature about its systematics can have a cladogram added. A single cladogram can be used on multiple articles.
    • Exception: Cladograms cannot be created in situations where the taxon has not appeared in at least one published analysis. Linnaean systematics cannot be translated into cladograms. Original research cladograms are not allowed.

Formats for cladograms:

  • The most significant features of cladograms can often be altered to fit specific articles with limited space.
  • The font size can be reduced with larger cladograms so that less space is taken up.
    • Default font size is 85% point size but can be changed between 75 and 100% upon request.
  • Line lengths affect how far the cladogram reaches across the page.
    • To fit images in the whitespace beside a cladogram with over 15 taxa a size below 90% is recommended, but sizes upwards that can be used to fill the cladogram across the whole article left-right.
  • Boxing a cladogram can allow for it to be positioned in line with text, and onto specific sides of a page.
    • Exception: Very large cladograms (~40+ taxa) should never be boxed, as they will take up far too much vertical space.
  • When specific formats are wanted please mention them in the cladogram request, otherwise Cladogram Creators will use their own discretion.

Images in cladograms:

  • Images like silhouettes or lateral views of skulls or life restorations can be added to cladograms
    • Note: when adding images, it is important to ensure that |middle is placed before the |thumb or equivalent, otherwise Firefox will render the images aligned to the bottom of the text and the taxon named will become uncentered.

Tips for Cladogram Creators:

  • Try to avoid edit conflicts by promptly replying to all requests that you intend to work on. Losing all your progress isn't fun.
  • Feel free to ask for help from others, we're all in this together.
  • Keep the OR rules in mind when creating cladograms. Don't add unpublished information to them.
  • Feel free to experiment with different features.


Requests

Protuberum cladograms request

Hello, I would like to request trees of the Traversodontidae for the purpose of the Protuberum article. The first one is of fig. 16 from (https://onlinelibrary.wiley.com/doi/full/10.1111/j.1475-4983.2008.00824.x) and the second fig. 11 from (https://www.sciencedirect.com/science/article/pii/S0895981124004358). Thank you Cellulosaurus (talk) 21:46, 12 March 2026 (UTC)

Here's the first one. I don't have access to the article for the second one. Cougroyalty (talk) 18:56, 13 March 2026 (UTC)

Diademodon

Trirachodon

Coriaria

Hello, I would like to request a phylogenetic tree for section C and B of the genus Coriaria. The study link is here: . It is fig. 2, section C (at the bottom). Thanks in advance. Alexeyevitch(talk) 05:38, 16 March 2026 (UTC)

Actually, ignore this... I've managed to figure it out. :-) Alexeyevitch(talk) 11:45, 17 March 2026 (UTC)

Rana and Lithobates

Hi, would anyone be able to code up fig 2 of . I would like the Lithobates and Rana trees to be coded up as two separate cladograms if that's ok. Hemiauchenia (talk) 23:26, 17 March 2026 (UTC)

Here you go. They look kinda squished. I wish the horizontal lines were longer. Cougroyalty (talk) 21:59, 18 March 2026 (UTC)
You can extend the horizontal lines by adding   to label1=. Alexeyevitch(talk) 22:45, 18 March 2026 (UTC)
You can also use |length=3em to lengthen the branches in each {{clade}} block. There is unfortunately no way to do this globally for the whole cladogram. You can tweak it to align the terminals but this is extremely tedious to do. As an example I edited the top part of the first cladogram with this edit which I've reverted.  —  Jts1882 | talk  08:21, 19 March 2026 (UTC)
@Alexeyevitch I agree, and that was something I used to do, until another editor started removing all the   and   from all of my cladograms. See the discussion here: Template_talk:Clade#Whitespace_around_labels
@Jts1882 Good to know. I suppose that will have to be the way. If I recall correctly, there is a way to globally increase the spacing for ALL cladograms. I thought you increased the padding for Template:Clade previously back in late 2024? Perhaps we could increase it just a tad more.
@Hemiauchenia Let me know if you would prefer to increase the spacing. I don't mind doing the tedious work. Cougroyalty (talk) 14:48, 19 March 2026 (UTC)
