How to Crochet an Adorable Amigurumi Brontosaurus: A Complete Step-by-Step Tutorial
If you’ve ever wanted to create a squishy, huggable dinosaur that looks like it belongs in a prehistoric forest made entirely of yarn, this tutorial is exactly what you’ve been looking for. Today we’re making a crochet amigurumi brontosaurus — one of the most charming and recognizable dinosaurs — using basic amigurumi techniques that work for beginners and intermediate crocheters alike. By the end of this post, you’ll have a complete pattern, tips for customizing your dino, and all the know-how you need to bring your very own Jurassic friend to life.
Why Crochet a Brontosaurus?
The brontosaurus (or more precisely, the apatosaurus, though brontosaurus has since been reinstated as its own genus — fun fact!) is one of those iconic long-necked, round-bodied dinosaurs that everyone instantly recognizes. In amigurumi form, that long neck becomes one of the most endearing features you can crochet. It gives the finished piece a graceful, almost whimsical quality that shorter or stockier animals just can’t match.
Dinosaur amigurumi patterns have exploded in popularity over the past few years, and for good reason. They make wonderful gifts for children and adults alike, they photograph beautifully for social media, and they push your crochet skills in ways a simple bear or bunny simply won’t. If you’ve been crocheting animals for a while and want your next project to feel genuinely exciting, a brontosaurus is a perfect choice.
Materials You’ll Need
Before we dive into the pattern, let’s gather everything. Having your materials ready before you start will make the whole process smoother and more enjoyable.
Yarn: Worsted weight (size 4) yarn in your main color. A soft, smooth yarn without too much texture works best for amigurumi because it shows the stitches clearly and gives a clean finish. You’ll need approximately 150–200 yards of your main color. You can also choose a contrasting color for the belly if you’d like a two-tone dinosaur.
Hook: A 3.5mm or 3.75mm crochet hook. Going down a hook size from what the yarn label recommends creates a tighter fabric, which prevents the stuffing from showing through — a classic amigurumi trick.
Safety eyes: Two 9mm or 12mm safety eyes. If you’re making this for a child under three years old, embroider the eyes instead using black yarn for safety.
Polyfill stuffing: You’ll need enough to stuff the body, head, neck, and legs firmly but not so tightly that the seams are stressed.
Stitch markers: These are a lifesaver in amigurumi. Use them to mark the beginning of each round.
Yarn needle: For sewing pieces together and weaving in ends.
Scissors
Optional: A small amount of pink or red yarn for an embroidered mouth, and felt or fabric paint for any extra details.

Pattern: Crochet Amigurumi Brontosaurus
Finished Size
Using worsted weight yarn and a 3.5mm hook, the finished brontosaurus measures approximately 10–12 inches from nose to tail and 7–8 inches tall (including the neck). Size will vary depending on your tension and yarn choice.
Part 1: The Body
The body is the largest piece and the foundation of your brontosaurus. It’s worked from the bottom up.
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4: Sc 2, inc rep around. (24 sts)
Rnd 5: Sc 3, inc rep around. (30 sts)
Rnd 6: Sc 4, inc rep around. (36 sts)
Rnd 7: Sc 5, inc rep around. (42 sts)
Rnd 8: Sc 6, inc rep around. (48 sts)
Rnd 9–18: Sc around all sts. (48 sts, 10 rounds even)
Rnd 19: Sc 6, dec rep around. (42 sts)
Rnd 20: Sc 5, dec rep around. (36 sts)
Rnd 21: Sc around all sts. (36 sts)
Rnd 22: Sc 4, dec rep around. (30 sts)
Rnd 23: Sc around all sts. (30 sts)
Begin stuffing the body firmly at this point. Continue to add more stuffing as you work the decreases.
Rnd 24: Sc 3, dec rep around. (24 sts)
Rnd 25: Sc 2, dec rep around. (18 sts)
Rnd 26: Sc 1, dec rep around. (12 sts)
Rnd 27: Dec around. (6 sts)
Fasten off, leaving a short tail. Use your yarn needle to sew the remaining 6 stitches closed, then weave in your end.
Part 2: The Head
The head is worked similarly to the body but is slightly more elongated to give that classic sauropod look — wide at the back and a little flatter at the snout.
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4: Sc 2, inc rep around. (24 sts)
Rnd 5–10: Sc around all sts. (24 sts, 6 rounds even)
Rnd 11: Sc 2, dec rep around. (18 sts)
Rnd 12: Sc around all sts. (18 sts)
Attach safety eyes between rounds 7 and 8, spaced about 8–10 stitches apart. If you’re embroidering eyes, do this after the head is complete and stuffed.
Rnd 13: Sc 1, dec rep around. (12 sts)
Stuff the head firmly.
Rnd 14: Dec around. (6 sts)
Fasten off, leaving a long tail for sewing. Close the remaining stitches and set aside.
Part 3: The Neck
The neck is crocheted as a long, slightly tapered tube. This is the piece that makes a brontosaurus look unmistakably like a brontosaurus, so take your time with it.
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4–6: Sc around all sts. (18 sts)
Rnd 7: Sc 4, dec rep around. (15 sts)
Rnd 8–12: Sc around all sts. (15 sts)
Rnd 13: Sc 3, dec rep around. (12 sts)
Rnd 14–22: Sc around all sts. (12 sts, 9 rounds even)
Stuff the neck as you go, but don’t overstuff — a lightly stuffed neck will curve more naturally and feel more poseable.
Fasten off, leaving a long tail for sewing. The wider end attaches to the body, and the narrower end will be sewn to the head.
Part 4: The Legs (Make 4)
The legs are simple and satisfying to work. All four are identical.
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc in BLO around. (12 sts) — this creates a little rim at the base of the foot
Rnd 4–10: Sc around all sts. (12 sts, 7 rounds even)
Stuff the leg. Don’t overstuff — legs that are moderately stuffed sit more naturally under the body.
Fasten off, leaving a long tail for sewing. Make all four legs before moving on.
Part 5: The Tail
The tail starts wide where it meets the body and narrows to a gentle point.
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4–6: Sc around all sts. (18 sts)
Rnd 7: Sc 4, dec rep around. (15 sts)
Rnd 8–10: Sc around all sts. (15 sts)
Rnd 11: Sc 3, dec rep around. (12 sts)
Rnd 12–15: Sc around all sts. (12 sts)
Rnd 16: Sc 2, dec rep around. (9 sts)
Rnd 17–18: Sc around all sts. (9 sts)
Rnd 19: Sc 1, dec rep around. (6 sts)
Stuff lightly, especially toward the tip so it remains flexible.
Fasten off, leaving a long tail for sewing.
Part 6: The Dorsal Bumps (Optional but Adorable)
Many crochet brontosaurus patterns include a row of small spinal bumps running from the base of the neck down to the tail. These are easy to make and add a lot of personality.
Make 5–7 small bumps:
Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc around all sts. (12 sts)
Rnd 4: Sc 1, dec rep around. (8 sts)
Leave unstuffed or stuff very lightly. Fasten off with a tail for sewing.
Assembly: Putting Your Brontosaurus Together
Assembly is where your project transforms from a pile of little crocheted shapes into a genuine dinosaur, and it’s honestly one of the most satisfying moments in any amigurumi project.
Step 1: Attach the tail. Pin the wide end of the tail to the back of the body, roughly centered, and sew it in place using your yarn needle and the long tail you left. Work around the entire opening, pulling gently to keep it snug. Weave in the end securely.
Step 2: Attach the legs. Position your four legs on the underside of the body — two toward the front and two toward the back, each pair spaced about 4–5 stitches apart from each other. The brontosaurus should look balanced and be able to stand on its own once the legs are attached. Pin them in place before sewing to check the spacing. Sew each leg on with at least two full passes around the opening for stability.
Step 3: Attach the neck. The neck attaches to the front-upper area of the body, angled slightly upward. If you stuff the neck lightly, you can position it at a gentle curve before sewing, which will give your brontosaurus a graceful, reaching pose. Sew the wider base of the neck securely onto the body.
Step 4: Attach the head. Sew the head to the narrow top of the neck. Angle it very slightly downward to mimic the way sauropods actually held their heads — more level than dramatically raised.
Step 5: Add the dorsal bumps. If you made the spinal bumps, line them up along the top of the body and base of the neck, spacing them evenly. Sew each one down securely.
Step 6: Embroider the finishing details. Use a small amount of black or dark yarn to embroider a simple smile below the safety eyes. A few small stitches are all you need. You can also add tiny nostril dots near the tip of the snout.
Tips for the Best Results
Working in a tight, even tension is the single most important thing you can do for amigurumi. If your stitches look loose or you can see stuffing through the fabric, try going down another half hook size or working more consciously to keep each stitch snug.
When stuffing, resist the urge to overstuff the body into a perfect sphere — a slightly softer middle gives the dinosaur a more natural, cuddly shape. The legs and neck should be firm enough to hold their position but not so tight that the yarn stretches.
If your neck leans or flops, you can insert a small length of pipe cleaner or chenille wire into it before stuffing, which allows you to pose the brontosaurus just the way you like.
For a two-tone color effect, switch to a lighter or contrasting yarn at round 9 of the body and work the belly section in that color before switching back.
Customization Ideas
One of the best things about crochet amigurumi is how infinitely customizable each pattern is. Here are a few directions you could take your brontosaurus:
You could make a whole family by scaling the pattern up or down. Using bulky weight yarn with a 5mm hook creates a larger brontosaurus perfect for a toddler to cuddle, while fingering weight yarn and a 2mm hook produces a miniature version that makes a beautiful keychain or ornament.
Color is another obvious playground. A realistic mossy green with a cream belly is always gorgeous, but pastel purple, dusty rose, or even rainbow-striped yarn would make an equally wonderful finished piece. Speckled or variegated yarn creates an almost scaly-looking texture that’s particularly striking for dinosaurs.
You could also add wings — yes, even though brontosauruses didn’t have them — to create a fantasy dragon-dinosaur hybrid that kids absolutely love. Small, semi-circular panels stitched to either side of the body transform your gentle herbivore into something a little more mythical.
