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 Don't add unpublished information to them.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

European Pelophylax frog taxonomy (so basically hell)

I'd like to have the cladogram shown in Figure 1 of Dufresnes et al (2024) made into a cladogram usable on Wikipedia please. Olmagon (talk) 21:52, 20 May 2026 (UTC)

The cladogram in Figure 1 isn't well-labelled, so I had to do some reading to clarify which were species and which were subspecies. And I'm still not quite sure how to represent all the P. ridibundus cf. ridibundus lineages A–M. I opted not to show the ones with just a capital letter, and just merged them.

Fordycetus cladogram request

Hello, is it possible to create a cladogram form the two phylogenetic trees in the description of the Squalodelphinid Fordycetus from the last word document of the supplementary data?https://tandf.figshare.com/articles/dataset/A_new_squalodelphinid_species_with_a_domed_supraorbital_process_from_the_Lower_Miocene_of_New_Zealand/32083398 Rangoon creeper (talk) 04:22, 15 June 2026 (UTC)

 Done — The strict consensus tree is a massive polytomy and thus hardly informative in this context. I've trimmed the 50% majority consensus tree to just platanistoids. Again, the rest of the tree isn't relevant for that page. -SlvrHwk (talk) 05:34, 15 June 2026 (UTC)
Thank you so much. Rangoon creeper (talk) 05:37, 15 June 2026 (UTC)
Thank you so much, how should I add it to the article properly? Rangoon creeper (talk) 05:40, 15 June 2026 (UTC)
Use the source editor to view and copy the code below, then paste it into the Fordycetus page, ideally under a properly formatted "Classification" section. -SlvrHwk (talk) 05:55, 15 June 2026 (UTC)
Okay, Thank you! Rangoon creeper (talk) 05:56, 15 June 2026 (UTC)

Great ape cladogram

Requesting a cladogram of the great apes based on Fig. 1 here. Please ignore the species split for humans, gorillas and orangutans. This is for the chimpanzee article. LittleJerry (talk) 22:27, 23 June 2026 (UTC)

You just want the great apes? Alright, simple enough (although this already exists on the chimpanzee page): Cougroyalty (talk) 22:01, 25 June 2026 (UTC)

Homo (human)

Pan

Pan paniscus (bonobo)

Pan troglodytes (chimpanzee)
