What’s new in Dinosauria Tree

The newly named Zimbabwean sauropodomorph now has a complete profile based on its formal description and museum announcement.

• NewAdded Musango matusadonaensis with its anatomy, size, healed injury, discovery story and scientific references.
• NewAdded Unaysauridae to the tree and connected Musango to this early sauropodomorph family.
• NewAdded an openly licensed Musango reconstruction, a generalized Lake Kariba fossil marker and a photograph of the discovery region.
• ImprovedAdded openly licensed Mamenchisaurus artwork to the M. hochuanensis gallery, clearly labelled as a reconstruction of the related species M. sanjiangensis.

The tree now combines faster image previews with a new time-scaled view of dinosaur relationships and fossil ranges.

• NewAdded a Timeline tree layout showing species fossil ranges against Triassic, Jurassic and Cretaceous time bands.
• ImprovedAdded separate Radial, Horizontal and Timeline layout buttons, while keeping Radial as the standard view.
• ImprovedAdded a compressed tree-only version of every dinosaur image, sized specifically for the small circular tree nodes.
• ImprovedNew dinosaur images automatically receive an optimized tree preview when the website starts or builds.
• FixedPrevented the tree from downloading and decoding full dinosaur-page artwork just to display an 18-pixel node image.
• FixedKept dinosaur images, labels and branch controls visible while dragging or zooming instead of hiding and restoring them after every movement.
• FixedRemoved a browser hydration warning caused by tiny rounding differences in the radial tree's branch positions.
• FixedRemoved the empty Troodontidae branch until a fully sourced member can be added to it.

The horned-dinosaur branch now covers more of the group’s early experiments with long horns, curled frills and rough facial bosses, alongside two historically debated names.

• NewAdded Diabloceratops eatoni with its distinctive paired frill spikes, Utah fossil location and Natural History Museum of Utah record.
• NewAdded the disputed Rubeosaurus ovatus with its original Montana frill and competing Styracosaurus interpretations.
• NewAdded Monoclonius crassus as a historical, dubious name without inventing a body size from its incomplete fossil.
• ImprovedAdded licensed artwork, fossil diagrams, museum information, map markers and scientific sources for all three profiles.
• NewAdded Achelousaurus horneri, the boss-faced Montana relative of Einiosaurus and Pachyrhinosaurus.
• NewAdded Albertaceratops nesmoi with its unusually long brow horns and Alberta discovery history.
• NewAdded Wendiceratops pinhornensis with its forward-curving frill ornaments and multi-individual Pinhorn bonebed.
• ImprovedAdded matching artwork backgrounds, fossil images, museum records, map markers and scientific evidence for the three new profiles.
• NewAdded Sinoceratops zhuchengensis, the first named ceratopsid from China, with its unusually ornamented skull and Zhucheng locality.
• NewAdded Avaceratops lammersi, a comparatively small Montana centrosaurine known from a partial skull and skeleton.
• NewAdded Coronosaurus brinkmani, the crown-frilled Alberta species first named as a kind of Centrosaurus.
• ImprovedExpanded the Centrosaurinae branch into Asia and added new scientific sources, museums, map regions and consistently framed artwork.

The former Recent page now explains what has changed across the website, while still keeping the dinosaur-addition browser.

• NewAdded this dated What’s New timeline based on the website’s real update history.
• ImprovedRenamed Recent to What’s New in the main menu so website updates are easier to find.
• ImprovedKept recently added and recently described dinosaurs together below the build notes.

The catalog passed 100 represented species with eight complete new profiles from several different branches of the tree.

• NewAdded Daspletosaurus, Mapusaurus, Tenontosaurus, Sauropelta, Caudipteryx, Borealopelta, Ornithomimus and Tawa.
• NewAdded fossil locations, museum information, scientific sources and licensed artwork for every new profile.
• ImprovedAdded Nodosauridae and Caudipteridae to place the new species more accurately in the tree.
• FixedChecked all primary dinosaur images for missing files, poor resolution and incorrect framing.

The homepage, Compare page and iPhone experience received visible improvements alongside three new dinosaur profiles.

• NewAdded Rajasaurus, Kosmoceratops and Sinosauropteryx with detailed evidence and museum information.
• NewAdded Dinosaur of the Day to the homepage.
• NewAdded an iPhone and iPad home-screen icon plus a simple installation guide.
• FixedFixed missing images on the Compare page.
• FixedFixed the Compare species list so names appear alphabetically.

This build made it easier to report mistakes and made the site more useful when scripts, links or filters do not behave as expected.

• NewAdded a Report an error form for corrections, source suggestions and website problems.
• NewAdded clearer information about what the dataset includes and how uncertain evidence is presented.
• ImprovedImproved dinosaur, source and recent-addition browsing with clearer filters and shareable page links.
• ImprovedAdded useful fallback content when interactive features cannot load.
• FixedFixed several page-state, filtering and static-site navigation problems.

Twenty dinosaurs were added across two releases, with richer profiles, lighter images and another round of tree improvements.

• NewAdded species including Suchomimus, Concavenator, Guanlong, Austroraptor, Nigersaurus, Majungasaurus and Torvosaurus.
• NewAdded more fossil sites, museum records and research references.
• ImprovedImproved image backgrounds and sizing so dinosaur artwork looks consistent without obvious borders or accidental cropping.
• ImprovedMade the interactive tree respond more smoothly while dinosaur images are visible.
• FixedAdded an image check to catch missing credits, low-resolution artwork and unsuitable framing before release.

The site was prepared for its public domain and Cloudflare hosting, followed by fixes for the export process and tree responsiveness.

• NewPrepared the website for public hosting, search engines, social sharing and the custom domain.
• ImprovedReduced work performed while dragging and zooming the tree.
• ImprovedMade the radial tree the standard view and changed the menu label from Explore to Tree.
• FixedFixed the Cloudflare build failure caused by missing static navigation files.
• FixedFixed additional lag caused when tree images entered the visible area.

A large catalog expansion arrived together with map clustering, making crowded fossil regions much easier to explore.

• NewAdded dozens of famous and newly described dinosaurs, including Giganotosaurus, Deinocheirus, Yutyrannus, Microraptor and Amargasaurus.
• NewAdded detailed artwork, fossils, locations and sources for the expanded catalog.
• ImprovedNearby fossil markers now form clusters at world view and separate as the map is zoomed in.
• FixedReduced overlapping map markers and labels in dinosaur-rich regions.

Several important dinosaurs received the deeper profile treatment established by the original reference pages.

• ImprovedExpanded Argentinosaurus, Patagotitan, Utahraptor, Compsognathus and Therizinosaurus.
• NewAdded more museum specimens, discovery history, fossil evidence and source-linked images.
• FixedAdjusted image fitting and map presentation for the expanded profiles.

The first complete version introduced an interactive way to explore dinosaur relationships, places, evidence and profiles.

• NewLaunched the interactive phylogenetic tree with zooming, dragging and clickable branches.
• NewAdded the world fossil map, dinosaur directory, comparison tool, global search and source library.
• NewAdded detailed species and clade pages with anatomy, size, timeline, museum and uncertainty information.
• NewAdded the first set of researched dinosaur artwork with visible creator and licence credits.
