In this appeal we are asked to reverse the judgment of the district court holding that principles of res judicata require dismissal of the appellant’s action brought under § 1983 and § 1985. In view of the insufficiency of the record we vacate the district court’s judgment and remand with instructions.
I.
On November 27, 1979, John Concordia filed this action in the federal district court for the southern district of Florida. In Count I of his complaint, Concordia alleged that on March 29,1977, J. Thomas Bendeko-vic, a Plantation, Florida police officer, stopped the plaintiff at a red light in Bro-ward County, Florida. Concordia alleged that Bendekovic, dressed in plain clothes and driving a van with no police markings, identified himself as a police officer and accused Concordia of committing a traffic violation. Concordia claims that a scuffle then ensued, that Bendekovic “acted outside of his jurisdiction and without authorization of law,” and that Bendekovic beat the plaintiff unnecessarily causing injury. Record at 2. In Count II of the complaint, Concordia alleges that the other individual defendant employees of the city conspired to cover up the deprivation of the plaintiff’s rights alleged in Count I.
On December 17, 1979, the defendants filed a Rule 12(b)(6) motion to dismiss the plaintiff’s action. They argued that the doctrine of collateral estoppel bars the plaintiff’s action. In their memorandum of law in support of their motion to dismiss, the defendants alleged (referring to an action in state court which Bendekovic had presumably brought against Concordia) that on August 9, 1977, Concordia had initiated a counterclaim against Bendekovic and the city of Plantation alleging that Bendekovic was liable for assault and battery. Exhibit A attached to that memorandum consists of an answer and counterclaim by Concordia to Case No. 77-9778 “Richardson, J” filed on August 9, 1977, in the Circuit Court of the 17th Judicial Circuit in and for Broward County, Florida. This counterclaim alleges that on March 29, 1977 Bendekovic assaulted Concordia and seeks damages. Counts II and III of this counterclaim allege that Concordia is entitled to damages from the city of Plantation as a result of this incident. Exhibit B of the present defendants’ memorandum consists of a true copy of a final judgment dated December 12, 1979 in Case No. 77-9778— Richardson granting plaintiff Bendekovic $96.50 compensatory damages and $1.00 punitive damages against Concordia and denying relief to Concordia on his counterclaim. On June 30,1981, the district judge ordered the present action dismissed based on the record described above. Judge Hastings stated:
In the instant case, Plaintiff John Con-cordia alleges that he was denied his civil rights in that he was beaten ‘unnecessarily,’ ‘willfully,’ and ‘with excessive force.’ His claim under Title 42, United States Code, Section 1983 makes substantially the same challenges which were raised by his Counterclaim in the prior State Court proceeding. Those issues ' having been *1075 considered and resolved against the Plaintiff may not be reconsidered here absent an allegation that plaintiff was denied a full and fair opportunity to litigate his claim in the State Court.
This appeal followed.
II.
It is well-established that where a party moves to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which relief can be granted and matters outside the pleadings are presented to and not excluded by the court, the motion is to be treated as if it were a motion for summary judgment under Rule 56.

Murphy v. Inexco Oil Co.,
In the case at bar, the defendants have raised the defense of res judicata
2
in the form of a Rule 12(b)(6) motion supported by the exhibits above mentioned. Res judicata, however, is not a defense under 12(b); it is an affirmative defense that should be raised under Rule 8(c).
Moch v. East Baton Rouge Parish School Board,
*1076
In determining the validity of a plea of res judicata, a court must determine whether the issue in the present action is identical to the one decided in the prior proceeding, whether the prior litigation reached a final judgment on the merits, and whether the party against whom the plea is asserted was a party or in privity with a party to the prior adjudication.
Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation,
The record consists of the defendants’ allegation that the issue of assault and battery was litigated in the state proceeding, a copy of Concordia’s counterclaim in Case No. 77-9778 — Richardson alleging essentially the same facts regarding Bendekovic’s alleged assault and battery on Concordia, and a copy of a judgment' in the state proceeding denying Concordia relief on the counterclaim. While this evidence suggests that the underlying issue of the present case was litigated in the state court, it does not satisfy all of the requisites necessary to invoke the doctrine of res judicata. For example, the' evidence does not indicate that the issue was actually litigated or that there has been a final judgment in the state proceeding. 4
Additional evidence, preferably a copy of the state trial court’s records, is required in order to apply the doctrine of res judicata in the context of either a Rule 12(b)(6) motion to dismiss or a Rule 56 motion for summary judgment. “As a general rule, a court in one case will not take judicial notice of its own records in another and distinct case even between the same parties, unless the prior proceedings are introduced into evidence.”
Guam Investment Co. v. Central Building, Inc.,
In the case at bar, the record of the state court proceedings was not introduced. No certified or exemplified copies of the pleading record or judgmental material were ever presented. The district judge accepted the copies of Concordia's state counterclaim and the copy of the state judgment as correct representations of what the state trial court’s record con
*1077
tained. This evidence does not satisfy the minimum requirement that the defense of res judicata appear from the face of the complaint.

III.
Because on remand the district court must now consider an issue that was the basis of its original opinion and that issue has been fully briefed and argued in this court, sound judicial administration requires us to discuss the merits of this claim. The parties’ central disagreement revolves around whether the federal district court should have given preclusive effect to issues raised in the state action. The state court counterclaim raised the issue of whether Officer Bendekovic was liable for assault and battery arising from the March 29,1977 incident. The issue properly framed for the district court on remand should not be the res judicata effect to be given to the state proceeding in this action brought under § 1983 and § 1985, but rather whether the state proceedings themselves satisfy the final judgment requirement and whether the state court actually and necessarily addressed the assault and battery question.
There can be no dispute that if the state proceedings satisfy the requirements for invoking res judicata, the district court must apply the doctrine in the present case. In enacting § 1983, Congress “was adding to the jurisdiction of the federal courts, not subtracting from that of the state courts.”
Allen v. McCurry,
Both parties in the present case apparently agree (though the record, discussed above, is deficient) that one of the issues before the state court in Case No. 77-9778 —Richardson consisted of whether Bende-kovic had assaulted Concordia on March 29,
*1078
1977. Ón remand, the district court should determine on the basis of a complete record whether this issue was actually litigated and whether the state court has rendered a final judgment. If the record indicates that a final judgment has been rendered and that the issue of Bendekovic’s alleged assault and battery was actually and necessarily litigated, the district court should reinstate . its order dismissing the case.

Notes
. The last sentence of Rule 12(b) provides:
If, on a motion asserting the defense numbered (6) to dismiss for failure of the pleading to state a claim upon which relief can be granted, matters outside the pleading are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 56, and all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 56.
Fed.R.Civ.P. 12(b).
. The doctrines of both res judicata and collateral estoppel deal with the issue preclusive effect of prior adjudications. “Under res judi-cata, a final judgment on the merits of an action precludes the parties or their privies from relitigating issues that were or could have been raised in that action. Under collateral estoppel, once a court decides an issue of fact or law necessary to its judgment, that decision precludes relitigation of the same issue on a different cause of action between the parties.”

. Indeed, since oral argument we have received two letters from the appellees in this case relating to an appeal of the state court decision. The letter dated August 16, 1982 contains a copy of an opinion of the Florida Fourth District Court of Appeal in Cases No. 81-672 and No. 81-913 styled Concordia, appellant, v. J. Thomas Bendekovic, Jr. and City of Plantation affirming a decision of Judge George Richardson, Jr. of the Circuit Court for Broward County. The decision is presumably, but not conclusively, an appeal from Case No. 77-9778— Richardson. The letter dated September 27, 1982 contains a copy of the state court of appeal’s order denying the appellant’s motion for rehearing in Cases No. 81-672 and 81-913. These decisions do not alter our conclusion based on the record that a question exists as to whether a final judgment has been rendered in a prior state proceeding.
. In
Chapman v. Aetna Finance Co.,
. In
Southern Jam,
we held that if state law would bar a § 1983 plaintiff from raising issues in a subsequent suit in state court, the plaintiff may not raise these claims in federal court. The present case is distinguishable from
Southern Jam,
in that Concordia brought his § 1983 suit before the state court had rendered a judgment and could not have removed the state action to federal court.
