Megalodon - Megatooth Fossils Found at the Calvert Cliffs of Maryland

Fossils here include:
Carcharocles subauriculatus aka chubutensis and Carcharocles Megalodon

So, you found a megalodon tooth.. Wouldn't you like to know how big the shark was that the tooth came from?
Click here for an easy way to find out!

Megalodons are among the most sought after teeth in the Calvert cliffs and other nearby Miocene exposures. However, before you go looking for a huge megalodon from the cliffs, you should be warned most of the meg teeth are in the 1 - 3" class in these Miocene exposures. Although larger ones are often found, you have a better chance at finding the large ones in the younger Pliocene exposures further south in the Atlantic coastal plain.


Carcharodon/Carcharocles sp.
White Sharks & Megatoothed Sharks

There is some debate as to what genus the ever-popular megatoothed sharks belong to.

If you want to know more about megalodons, their lineage, images, etc... Please click here to go to the megalodon gallery page for much more information and images on Megalodon
?Carcharodon subauriculatus (Agassiz, 1839) aka chubutensis (Ameghino, 1906a)
(Megatooth Shark)
Identification based on Kent (1994) & Purdy et al (2001).
This species is thought to have evolved directly into C. megalodon. The only difference is the tiny cusplets
This species is only found in the early to middle Miocene. This species may be thought to have evolved from C. subauriculatus, however Purdy et al (2001) suggests C. chubutensis is synonymous with C. subauriculatus.

Distinguishing the difference between small megalodons and subauriculatus can be tricky. Juvenile megalodons can also have cusps on their teeth. Therefore, some subauriculatus identified below could be juvenile megalodons.
The 1st megatooth shark I found!
Notice this chubutensis has very tiny "nubs" for cusps. It almost looks like a cross between a megalodon and a chubutensis.

Based on this tooth, the size of the shark it came from was probably around 21 feet in length.

Formation:
  • Calvert, Plum Point member
    Age:
  • Early - Middle Miocene ~ 18-15 m.y.
    Location:
  • Plum Pt., Calvert Co., MD
    Size:
  • 2.75" (70mm) slant height
  • megatooth fossil shark tooth - miocene - calvert cliffs
    This is a chipped C. subauriculatus tooth.
    It's not a megalodon because of the small cusps on the side of it.

    Formation:
  • Calvert
    Age:
  • Middle Miocene ~ 18-15 m.y.
    Location:
  • Chesapeake Bay Area
    Size:
  • 2.25" (57mm) slant height
    Date:
  • September 2012 TRIP
  • Amy saw this razor sharp chubutensis sticking out of the sand and thought it was whole!
    It broke her heart when she lifted it out of the sand.
    This is the summers official heartbreaker tooth.

    I didn't know Chubbys got this big!

    Based on this tooth, the size of the shark it came from was probably around 40 feet in length.


    Formation:
  • Choptank
    Age:
  • Early - Middle Miocene ~ 18-15 m.y.
    Location:
  • Near Parkers Creek, Calvert Co., MD
    Size:
  • ~5 1/16" (129mm) slant
    Date:
  • Summer 2001
  • This is a small chipped Chubutensis posterior (from the rear of the mouth).
    You can tell it's a Chubby, due to the tiny "cusp" at the edge of the tooth

    Formation:
  • Calvert, Plum Point Member
    Age:
  • Middle Miocene ~ 18-15 m.y.
    Location:
  • Willows, Calvert Co., MD
    Size:
  • 1 1/8" (28.5mm) slant height
    Date:
  • Summer, 2001
  • This is a labial view of a broken lower lateral tooth.



    Formation:
  • Calvert, Plum Point member
    Age:
  • Early - Middle Miocene ~ 18-15 m.y.
    Location:
  • Plum Pt., Calvert Co., MD
    Size:
  • If complete, ~2 1/2" (63mm)
  • We found a tiny one... This guy was dug out of a chunk of fallen Zone 10 in the Calvert Formation.
    It appears to have some feeding damage on the tip.


    Formation:
  • Calvert, Plum Point member, Zone 10
    Age:
  • Middle Miocene ~ 16-15 m.y.
    Location:
  • Randle Cliff, Calvert Co., MD
    Size:
  • 1 1/4" (30mm) slant height
  • ?Carcharodon megalodon (Agassiz, 1843)
    (Megatooth Shark)

    Identification based on Kent (1994) & Purdy et al (2001). Obviously, this is the most famous prehistoric shark. It has the largest teeth, was twice the size of a Great White, and included whales in its diet!
    They lived from the Miocene and became extinct in the Pliocene. I sure am glad they're dead!

    Date:
  • January 2004.
  • The left tooth was found by snorkeling , The right one is a small but almost perfect anterior, except for the feeding damage on the tip.
    This was pulled out of a chunk of fallen zone 10 of the Calvert formation.

    Based on these teeth, the size of the sharks these teeth came from were probably around 15 feet in length.

  • Left is Choptank. Right is Calvert, Plum Point member, Zone 10

  • Middle Miocene ~ 18-15 m.y.
    Location:

  • Both have a 1 7/8" (47mm) slant height
    Date:
  • Left is from spring 2002, right is from spring 2000.
  • These are three small lateral megs. The left one is a labial view of a marble looking tooth. The right one is a lingual view of the first nearly complete C. megalodon tooth Amy found. The left two are labial views.

    Formation:
  • Calvert, Plum Point Member
    Age:
  • Middle Miocene ~ 18-15 m.y.
