How to Bone Identifier
Follow these simple steps to get instant AI-powered identification
Take a clear photo of the bone you want to identify and upload it directly in your browser â no app installation needed. For best results, photograph the bone from multiple angles on a plain, contrasting background. Sign in with Google to get started quickly and securely.
Our advanced AI examines the bone's morphology, size cues, surface texture, joint features, and distinctive anatomical landmarks to make an identification. It cross-references thousands of vertebrate and invertebrate skeletal reference points to determine species group, bone type, and likely origin. This happens in just a few seconds.
You'll receive a thorough breakdown including the likely animal group or species, the specific bone name and its anatomical location, ecological context, and what the bone might tell you about the animal's lifestyle. Unlike tools that only give you a label, IdentifyThis.app provides rich contextual explanations so you truly understand what you've found.
Alternative Methods
Field Guides & Osteology Reference Books
Printed osteology guides such as 'Mammal Bones and Skulls' by David Braun or regional wildlife bone atlases can be invaluable for hands-on identification. These resources often include size measurements and comparative diagrams but require significant time and expertise to use effectively.
University or Museum Comparative Collections
Natural history museums and university zoology departments maintain reference skeletal collections that experts use to compare found bones directly. Access is typically limited to researchers, but many institutions offer public inquiry services via email with photos.
Online Osteology Communities
Forums and social media groups such as Reddit's r/bonecollecting or Facebook's Bone ID groups have knowledgeable communities that can help identify bones from photos. Responses can be slow and vary in accuracy depending on who is online, but enthusiastic collectors often provide surprisingly detailed answers.
Wildlife Biologists & Veterinarians
Local wildlife biologists, game wardens, or veterinarians with anatomy experience can often identify bones from photos or in person. This method is especially useful if you suspect the bone may be of legal or conservation significance, such as from a protected species.
Forensic Anthropology Resources
For bones that may potentially be human â or to definitively rule that out â forensic anthropology departments at universities can assess skeletal material. Law enforcement and forensic professionals are the appropriate contacts when human origin cannot be confidently excluded.
Photo Quality Tips
- âPlace the bone on a plain, high-contrast background such as a white sheet, dark cloth, or clean pavement to help the AI distinguish it clearly from surroundings.
- âPhotograph the bone in natural daylight or bright, even artificial light to reveal surface texture, colour variations, and fine anatomical details without harsh shadows.
- âInclude a common size reference object beside the bone â a coin, ruler, or pen â so the AI can better gauge scale, which is critical for species-level identification.
- âCapture multiple angles: a top view, a side profile, and if applicable, the joint surfaces or internal cavity of a long bone, as different features are visible from different perspectives.
Best Practices
- âĒClean the bone of mud or debris before photographing, as obscured surface features are one of the most common reasons for identification errors.
- âĒIf photographing a skull, include shots of both the top (dorsal view) and the underside (ventral view), as dental arcade and foramen patterns are highly diagnostic.
- âĒAvoid using flash directly on bleached or very white bones as it can wash out important texture details â diffused or side-angled lighting works much better.
- âĒIf the bone is fragmented, photograph all pieces together in approximate anatomical position as well as individually, giving the AI the best chance of recognizing the overall structure.
What Can Our Tool Recognize?
AI-powered recognition across multiple categories with high accuracy.
Identify bones from deer, foxes, rabbits, coyotes, bears, cattle, and dozens of other mammal species commonly found in forests, fields, and rural areas.
Recognize the distinctive hollow, lightweight bones of birds, including wing bones, keeled sternums, and skulls from raptors, waterfowl, songbirds, and more.
Distinguish vertebrae, jaw bones, and skeletal elements from snakes, lizards, turtles, frogs, and other cold-blooded species found across diverse habitats.
Identify otoliths, vertebrae, jaw bones, and fin spines from freshwater and saltwater fish species, useful for anglers, ecologists, and coastal beachcombers.
Get detailed identification of animal skulls based on dental formulas, orbit size, sagittal crests, and other cranial features that reveal species and diet.
Identify isolated teeth and dental fragments, which are among the most species-diagnostic skeletal elements due to highly variable morphology across animals.
Recognize femurs, tibias, humeri, and other long bones from the appendicular skeleton of vertebrates, with identification based on epiphyseal shape and shaft features.
Analyze heavily weathered, ancient, or fragmentary bone material that may come from archaeological sites, paleontological deposits, or long-exposed outdoor environments.
Why Choose Our Identification Service?
The most accurate, fast, and privacy-focused identification tool available online.
IdentifyThis.app is entirely web-based â there's nothing to download, install, or update. Open it on your phone, tablet, or desktop, sign in with Google, and start identifying bones immediately wherever you found them.
Instead of just returning a species name, our AI provides detailed context: what bone you're looking at, what animal it came from, why those features led to that conclusion, and interesting ecological notes about the species. You actually learn, not just get a label.
Your subscription unlocks identification across every category on IdentifyThis.app â plants, insects, mushrooms, rocks, animals, birds, fish, and more. No need for five separate specialist apps when one affordable tool does it all.
At just $3/week or $10/month for unlimited identifications, IdentifyThis.app costs a fraction of niche competitors. PictureThis charges $39.99/year for plants only; we cover everything including bones for a fraction of that price.
Your uploaded bone photos are not stored or used to train models beyond your session â your finds stay private. This matters especially for those who may have found bones in legally sensitive contexts or simply value their digital privacy.
Whether you're a curious hiker who stumbled across a skull, a student studying comparative anatomy, or an experienced bone collector building a reference library, the AI scales its explanation depth to be genuinely useful at every knowledge level.
Since it's browser-based, IdentifyThis.app works on iOS, Android, Windows, Mac, and Chromebook with no compatibility issues. Whether you're in the field on your phone or at your desk on a laptop reviewing a find, it just works.

Many people stumble upon bones while hiking, gardening, or walking on beaches and want to know what animal they came from. Our AI can analyze the bone's shape, size cues, and surface features to give you a likely species and bone type identification.
One of the most common and urgent bone identification questions is distinguishing human bones from animal bones, which can have legal and ethical significance. Our AI provides an informed assessment, though for any bones suspected to be human, contacting law enforcement is always recommended.
Skulls are among the most fascinating and information-rich skeletal elements, revealing diet, sensory adaptations, and species identity through dental formulas, eye socket size, and cranial shape. Our bone identifier specializes in skull identification across mammals, birds, and reptiles.
Dogs frequently discover bones on walks, in yards, or in wooded areas, and owners often want to know if it's safe and what animal it's from. Our identifier can help determine the likely source species so you can make informed decisions about the find.
Deer are among the most commonly encountered large mammals in North America and Europe, and their bones â ribs, vertebrae, leg bones, and skulls â are frequently found by hunters and hikers alike. Our AI can identify individual deer bone elements with anatomical detail.
Bird bones are highly distinctive due to their pneumatization (hollow structure) and unique joint shapes evolved for flight, making them identifiable even in fragmentary form. IdentifyThis.app's AI is trained to recognize avian skeletal features across common and uncommon species.
