Purdy et al (2001) included three species:ĭ. Several variations of Dasyatis are found and three + species are likely represented. Stingray teeth are abundant in the Pungo River, less so in the Yorktown. laevis MITCHILL, 1817.ĭASYATIDAE Jordan, 1888 - Whiptail Stingraysĭasyatis. These teeth are common in Pungo River sediments and abundant in basal Yorktown Multiple genera/species are represented by teeth and thorns, Purdy et al (2001) report two teeth (Yorktown unit 1) attributed to R. Purdy et al (2001) report this genus as present in Pungo River units 4 & 5 extensive collecting by this author has failed to find an example which might not be better referred to Rhynchobatus. RHINOBATIDAE Müller & Henle, 1837 - Guitarfishes Purdy et al (2001) make no mention of this taxon. This genus no longer inhabits western Atlantic waters. Rhynchobatus teeth are regularly found when sifting Pungo River and lower Yorktown sediments. RHINIDAE Müller & Henle, 1841 - Wedgefishes A single Pungo River specimen is known that would appear to represent a Propristis rostral spine. Purdy et al (2001) deemed this rostral spine-design as juvenile Pristis - they compare better with the Anoxypristis tooth-design. Accompanying image is an Eocene example.Īnoxypristis. Purdy et al (2001) reported one Yorktown (unit ?1) specimen with a posterior groove as Pristis cf pectinatus LATHAM, 1794, three others (lacking the groove) were deemed Pristis juveniles. If this is the case, the available material is much different than was available for the shark taxa.īody image linked to extant batoids, tooth image to fossil teeth ![]() If I recall correctly, the batoid section of this publication was written many years ago by Robert Meyer and released virtually as is. To date, I have encountered over 20 'types' of Mobula teeth alone, which likely represent only two or three species. There was very little published on this subject, and identifying these finds proved very difficult. They have yielded a large number of small (1 to 4 mm) elasmobranch teeth and dermal denticles. ![]() During the early 90s, the author spent extensive time collecting, cleaning and processing Miocene & Pliocene sediments from the mine. Depending on patience and eyesight, Aurora can provide a quantity of beautiful and different teeth or the repetition of picking up one homogeneous myliobatoid crusher tooth after another.
