mystery dino CAL: plesiosaurus!


The 5th dinosaur is Nessie the Plesiosaurus!

The name ple­siosaurus derives from Greek words for “almost-lizard”. Con­trary to pop­u­lar imag­i­na­tion, ple­siosaurus were not great swim­mers and could not breathe under­wa­ter. It also laid eggs and buried them in soft sand like sea tur­tles. It mea­sured twice as long as a horse, and weight­ed twice as much as a pig. (source)

Here are two Nessies bob­bing along in the ocean. The larg­er blue ver­sion is made with bulky weight yarn and 4 mm hook, and the pale green ver­sion is made with the usu­al worsted weight yarn and 3.5 mm hook.

As you may notice, ple­siosaurus is cro­cheted most­ly the same as bron­tosaurus, but with flip­pers. I took some process pic­tures to show you how I got the flip­pers on :D

I used:

  • Small amount of worsted weight yarn
  • 3.5 mm hook
  • 2.5 mm hook (option­al, but it’s eas­i­er for weav­ing in ends)
  • Sewing nee­dle, black thread and seed beads for eyes


Make body, neck and tail the same as bron­tosaurus, as follows.

The body begins as a circle.

Round 1: ch 2, 6 sc in 2nd sc from hook, don’t join in round.

Round 2: 2 sc in each sc around (12 sc).

Round 3: [sc in next sc, 2 sc in next sc] six times (18 sc).

Round 4: sc in next 17 sc, sl st in next sc, don’t fas­ten off.

Neck & head: ch 8, [yo, pull up a loop] twice in the 3rd ch from hook, pull through all loops on hook, ch 1 (pop­corn stitch made), 2 sc in the same ch as pop­corn stitch, 1 sc in each ch down the neck, con­tin­ue on to back of the dinosaur…

Back: Fold body in half, skip the sc imme­di­ate­ly next to the neck ch (on both sides), sl st in next sc and each sc through both lay­ers of body across back, con­tin­ue on to tail…

Tail: sl st in last st through both lay­ers on back, ch 5, sl st in 2nd ch from hook, sl st in next ch, sc in last 2 ch of tail, sl st in a space between the 3rd and 4th round in the body (bel­ly part of the dinosaur). Fas­ten off.


ch 5, sl st in 2nd ch from hook, sc and hdc in next ch, sc in next ch, sl st in next ch, pull yarn through loop, leav­ing a tail 18″-20″ long, cut yarn. It will look like this.

With right side fac­ing, insert hook from the back of the dinosaur into a stitch where you want to posi­tion the first set of flip­pers, between the 2nd and 3rd rounds of body, like so…

Then, pull the yarn tail of the flip­per just made through the body, like so…

With the wrong side of the dinosaur fac­ing and the dinosaur posi­tioned upside down, insert hook through the body again in the same stitch, then pull up a loop using the yarn tail, like so…

Then, ch 5, and con­tin­ue with stitch­es for the oth­er flipper.

After the last sl st made in flip­per, pull out yarn tail, and weave it into the body through the same stitch where the flip­pers are attached.

Repeat as the start of the oth­er flippers.

With right side fac­ing and the dinosaur right side up, insert hook from the back in a stitch between rounds 2 and 3 of body, where you want to posi­tion the oth­er set of flip­pers, like so…

Repeat as the oth­er set of flippers.

Sew on eyes, and we’re done! :)
