What Valentine's Day gift do you get that special someone who really digs science? Instead of a dozen roses, how about buying a bouquet of plush dinosaurs? In lieu of chocolate, why not purchase "pi plates" decorated with math equations? In preparation for Feb. 14, Live Science has put together a geeky gift guide for your science-loving valentine. However you and your beloved decide to celebrate, we hope it's chock-full of paleontology, astronomy and biology.

Surprise your valentine with a colorful bouquet of creatures from the Mesozoic era. This plush gift includes six dinosaurs in all, including Tyrannosaurus rex, Triceratops and Apatosaurus. Then, you can get into a lively (but loving) discussion about whether the long-necked sauropods Apatosaurus and Brontosaurus are from the same genus, or whether they are completely different and need a new family tree.

The bouquet can be purchased at ThinkGeek, and costs $50. (Photo credit: ThinkGeek)

Show your geeky partner the depth of your eternal love by naming a star in their honor. The International Star Registry has several gifts for sale, including the $54 "Custom Star Kit," that includes a personalized certificate with the star's name, date and coordinates, as well as a star chart with the named star in red.

Granted, the registry isn't recognized by the International Astronomical Union, the scientific organization that officially names stars, but it's still romantic to go stargazing with your sweetheart and find the pinpoint of light that shares their name.

Does your valentine make your heart skip a beat? We hope not — that means you could be experiencing premature ventricular contractions! They're no big deal, but the Mayo Clinic recommends that people seek treatment if it happens frequently, as it could be a sign of an underlying health condition.

Either way, this beautiful heartbeat scarf will be a sure sign of your affection, and a great way to brighten your partner's wardrobe.

The amazing tardigrade can survive in the vacuum of space, and it can also decorate a necklace or keychain that your geek will treasure. Pull back the tardigrade's plates to see its internal anatomy, including its digestive, nervous and reproductive systems. Notice its muscles, and be sure to share with anyone who will listen that the tardigrade has been found all over the planet, from ocean trenches to the tips of mountains.

The Higgs boson is thought to give all other particles mass, and this elusive particle also inspired artists to design a mesmerizing watch. On Valentine's Day, watch the watch's second hand spin around, representing the Higgs decaying into other bosons, according to the Unemployed Philosophers Guild.

The watch is for sale for $42.95. (Photo credit: Amazon.com)

Now that the "X-Files" are back on TV, what better way to celebrate an alien-filled Valentine's Day than at the UFO Treehotel in Sweden? To enter the spaceship, guests climb up a ladder that looks eerily like a tractor beam. It's a romantic getaway for a pair, but fits up to five people (two adults and three children) who can hang out in the flying saucer's bedroom, bathroom and living area.

Treehotel has several other intriguing suspended rooms, including a twiggy bird's nest and the Mirrorcube. Book the UFO room now at Treehotel for about $685 a night for two people. (Photo credit: Treehotel)

Surprise that special someone by naming a Madagascar hissing cockroach after him or her. The Bronx Zoo still has tens of thousands of roaches that need names, and it will give you a reason to visit the world-class zoo. (Though be aware, some people name the roach after their ex-partners, so this tradition goes both ways!)

For $10, the zoo will send a digital certificate to your sweetie. For $25, you can get a printed roach certificate and a box of chocolate made by the Nunu Chocolate Co. in Brooklyn. (Photo credit: WCS/Bronx Zoo)

People often eat sweets with their sweetheart on Valentine's Day. Let paleo-beasts sweeten that experience with a dinosaur-patterned rolling pin. The laser-printer-engraved rolling pin can be used on dough, clay and even noodles, according to RainbowRollingPins. But if used on pies or cookies, feel free to review the scientific names of the dinosaurs on your delicacies, including a Tyrannosaur, sauropod, Stegosaurus, Triceratops and a Velociraptor.

Discuss the enigma of the brain as you sip hot tea (or something stronger) while using these brain specimen coasters. The set of 10 shows different slices of the brain. On a slightly less romantic note, it's also a great conversation starter for what to do with your brain once you die — check out the NIH Neurobank to learn more about your options.

The coasters can be purchased at ThinkGeek, and cost $19.99. (Photo credit: ThinkGeek)

Once you have your dinosaur-patterned pies, what better way to serve them than on "i eight sum pi" plates? These microwave- and dishwasher-safe plates come printed with a fun equation that has a secret meaning.

A set of two plates at UncommonGoods costs $35.  (Image credit: UncommonGoods)
