What is a Brontosaurus burger?

The Brontosaurus, the “Thunder Lizard” was once one of the largest and most popular dinosaurs. This quadruped sauropod from the Late Jurassic had a long thin neck, bulky heavy torso and a long whip-like tail. This herbivore is estimated to have been up to 22 metres long and weighed more than 15 tonnes.

Some years ago, it was feared that the Brontosaurus was lost. Researchers believed that the Brontosaurus was closely related to an Apatosaurus, and probably was actually an Apatosaurus and not a separate species of dinosaur. It wasn’t until 2015 that further research showed that the Brontosaurus is actually a separate genus from the Apatosaurus.

But what is the Brontosaurus burger? this was a philosophical question for me. Is it a vegetarian or vegan burger for a herbivore? Might be. Are Brontosaurus burgers made of Brontosaurus meat? I hope not (it may make sourcing ingredients difficult, and I would probably go vegan before I ate dinosaur meat).

In our interpretation, Brontosaurus burgers are dino burgers that are full of goodness and very large, like a Brontosaurus.

What’s in Brontosaurus burgers?

Anything you like – there are no rules. Brontosaurus burgers got their name from their colossal size.

To make them something special, we’ve come up with a slightly unusual combination of toppings for our Brontosaurus burgers. Perhaps it is something your little dinosaur fan will appreciate, though it might be one more for the adults.

We’ve taken regular burger (brioche bun and burger patty) and added balsamic onions, aioli, bacon (optional), pieces of brie, slices of apple and some crisp, fresh rocket. Trust me, it is delicious.

For a nice twist, serve with sweet potato fries or wedges with sweet chilli sauce and sour cream.

What kind of dinosaur is the Compsognathus?

The Compsognathus or “elegant jaw” is a small, carnivorous therapy dinosaur. It lived in Europe about 150 MYA, in the late Jurassic period. In fact, Compsognathus was the first nearly complete dinosaur that was ever found. It is also one of the smallest, at about the size of a turkey.

The first fossils of the “Compy” were found in Germany by Joseph Oberndorfer. He did not tell anyone exactly when or where he found the fossils to prevent others from exploiting the site. It is now believed that it came from the Solnhofen limestone, the same site where the first Archaeopteryx fossils with feather impressions and pterosaurs with imprints of their wing membranes were also found.

We actually have a review of a museum coming soon. It’s not far from where the Compsognathus was found and capitalises on the connection.

Oberndorfer lent his specimen to Johann Wagner, a palaeontologist who named it and published descriptions of it. He did not recognise it as a dinosaur, instead calling it “most curious form among the lizards”. This has since proved false.

We also know that the Compy was a carnivore: the fossilized bones of a small, prehistoric mouse were found in the “stomach” of the Compsognathus fossil. This mouse was quite fast; the Compy must have also been fast with good eyesight in order to be able to catch his prey.

What’s on Compsognathus cheeseburgers?

While the discovery of the Compy is quite complex, Compsognathus cheeseburgers are quite simple. Simplicity is actually the key to dino burgers.

Our Little dinosaur aficionado is still a picky eater. She loves meatballs, but this Compsognathus cheeseburger was the first burger she has eaten (yes, not even the burgers from the restaurant with the golden arches could tempt her). Simplicity was key.

No salad. No onions. No pickles or gherkins. Just cheese, meat and bread with a little ketchup. For fun, we added some (optional) bacon (which she wanted removed halfway through). Otherwise, it’s minimum fillings for picky little Compsognathus.

Serve with your favourite fries (we recommend sweet potato, but your little dinosaur fan might not like them either).

Any why are they Compsognathus cheeseburgers? Because Compsognathus starts with “c”.

Spread the top half of the brioche bun with mayonnaise and place on top to complete your burger.

For the Compsognathus Cheeseburger

  1. Grill your burger patty and bacon until done to your liking. After turning your patty for the last time, place your slice of cheese on top.

  3. Spread ketchup on half of your bun and top with the bacon and patty/cheese and the top of the bun.
